Agreement


What is agreement?

Certain words are connected with each other, and because they are connected, they must agree or match in a specific way. The two main forms are listed below.

Subject-Verb agreement

Verbs must agree with their subjects in regards to the number. If there is one subject (singular), the verb must reflect that by being in singular form. If there is more than one subject (plural), the verb must be in its plural form (Lester and Beason 123).

Example

He welds every day.
He is singular, and welds is the singular form of "to weld".
They weld every day.
They is plural, and weld is the plural form of "to weld".


Exceptions

With compound subjects that are joined by "and", the verb is always plural. When joined by "or", "either", "neither", "nor", "not only", and similar words, the verb agrees with the closest subject (Lester and Beason 134).

Example

Angie and Tyler play games at the park.
Angie and Tyler together make two people, so the verb "to play" is plural.
Neither Angie nor Tyler plays games in the park.
Angie is separate from Tyler in this sentence, so the verb "to play" is singular.


Pronoun-Antecedent agreement

Pronouns must have the same number and gender as the word they are replacing (Lester and Beason 167).

Example

Tim says that he is proud of himself.
"He" and "himself" are both masculine and singular like Tim.
Andrea says that she is proud of herself.
"She" and "herself" are both feminine and singular like Andrea.
The twins say that they are proud of themselves.
"They" and "themselves" are plural and genderless like "twins".


Exceptions

Indefinite pronouns which talk about unspecified nouns must agree in number (Lester and Beason 169).

Example

Both say that they are proud of themselves.
"Both" is always plural, so it is matched with the plurals "they" and "themselves".
Somebody says that he or she is proud of him- or herself.
"Somebody" is always singular, so it is matched with the singular; however, since the gender is unknown both genders should be indicated. This makes the sentence wordy and should be avoided by keeping indefinite pronouns plural as often as possible.

Clauses

What is a clause?

A clause is a group of words with a subject and a verb. There are a few different types of clauses as outlined below (Lester and Beason 48).


Independent

Independent clauses are entire thoughts that can stand on their own.


Example

The boys ate lots of pie.
"Boys" is the subject, "ate" is the verb. If that sentence was stated on its own, it would make sense.


Dependent

Dependent clauses are unable to stand on their own. If they are not attached to an independent clause, it will not make sense. There are three types of dependent clauses below, many of which start with words that can help identify them (Lester and Beason 49).

Adjective Clauses

Adjective clauses modify the nouns they follow and start with one of the following words: "who", "whom", "whose", "that", and "which" (Lester and Beason 55).

Adverb Clauses

Adverb clauses modify verbs by giving information about where, when, why, or how and begin with subordinating conjunctions (Lester and Beason 50).

Noun Clauses

Noun clauses work as noun phrases, taking the place of single nouns, and often begin with "that" or words starting with "wh" (Lester and Beason 61).

Example

Andrew sang the song that he wrote.
"Andrew" is the subject, "sang" is the verb, "the song" is the direct object, and "that he wrote" is an adjective clause. Notice that there is a subject, "he", and a verb, "wrote". "That he wrote" would not make sense as statement on its own, so it is dependent.
Alex poured water on the plants because the ground looked dry.
"Alex" is the subject, "poured" is the verb, "water" is the direct object, "on the plants" is a prepositional phrase, and "because the ground looked dry" is the adverb clause. Notice that there is a subject, "ground", and a verb, "looked". "Because the ground looked dry" would not make sense on its own.
I don't know if the baby will be a boy or a girl.
"I" is the subject, "don't know" is the verb, "if the baby will be a boy or a girl" is the noun clause. Notice that there is a subject, "baby", and a verb, "Will be". "If the baby will be a boy or a girl" would not make sense as a statement on its own, so it is a dependent clause.


Restrictive Clauses

Adjective clauses can be either restrictive or nonrestrictive. A restrictive clause defines some element of the noun it modifies. It is necessary for the noun to have meaning in context.

Example

The shirt that I was wearing last night got ripped.
"The shirt" is the noun being modified. There are many shirts, and the speaker likely owns quite a few shirts. To understand which shirt the speaker is referring to, the restrictive clause "that I was wearing last night" is necessary.


Nonrestrictive Clauses

A nonrestrictive clause gives information that could be useful, but the noun would make sense without the information.

Example

The shirt, which I bought at a thrift store, got ripped.
"The shirt" is the noun being modified. The speaker may own more than one shirt from a thrift store, and the nonrestrictive clause, "which I bought at a thrift store", does not define which shirt from the thrift store it was. The information might be useful, but it is unnecessary.

Parts of Sentences

What is a sentence?

Sentences are groups of words that can express complete thoughts on their own without relying on context or requiring a question to be asked first (Lester and Beason 45).

Types of Sentences

There are four types of sentences: declarative sentences that make a statement and end with a period, interrogative sentences that ask questions and end with a question mark, imperative sentences that make commands or mandates and are punctuated with either periods or exclamation marks, and finally, exclamatory sentences that are statements punctuated with an exclamation mark (Lester and Beason 46-47).

Examples

I like books.
This is a declarative sentence. No context is needed for it to be understood.
Do you like books?
This is an interrogative sentence because it asks a question.
(You)Buy that book.
This is an imperative sentence, and the (You) at the front is understood to be there even though it would not be said.
I love books!
This is an exclamatory sentence, placing emphasis on the fact that I love books.


Parts of Sentences

Sentences are assembled from different pieces. Knowing the various pieces can make a complicated sentence easier to understand.

Subject

The subject is who or what is doing the action in the sentence or is the topic of the sentence if no action is being done. There are two categories of subjects: simple, the noun or nouns that can be modified, and complete, the noun and its modifications. Subjects must have the correct agreement with verbs. This is also known as a noun and a noun phrase (Lester and Beason 23).

Verb

Verbs either provide the action a subject is doing or describe the subject. Like subjects, there are two categories of verbs: simple, the verb and any helping verbs, and complete, the verb and its complements (Lester and Beason 27).

Complements

Complements are nouns or adjectives that follow a verb or preposition so that a sentence can make sense. This includes direct objects, which receive the action of the doer and indirect objects, which receive the direct object.

Example (The subjects are italicized, verbs are bold, and complements are underlined.)

Anthony gave his car a quick tune up.
Anthony is the subject because he is the thing doing something. In this case, the action was to give something to something. The direct object receives the action, which in this case is a tune up. And the indirect object is the thing that ultimately receives the modified action of the verb and in this case is the car, which is receiving the tune up that is being given by Anthony.
Jacob handed Edward the pen and paper.
Jacob is the doer of the action, which is handing something to someone. The pen and paper are the items being acted upon, and Edward is the one receiving the pen and paper.

Parts of Speech

Parts of Speech

Parts of speech are elements that are used to make up clauses, phrases, subjects, and sentences. There are many parts of speech and they are listed below in alphabetical order.

Adjective

Adjectives describe or modify nouns and pronouns, and act as predicate adjectives by describing the subject of linking verbs. When modifying nouns, the adjective always come before the noun; when acting as predicate adjectives, they always follow the verb (Lester and Beason 8).

Examples(The adjectives are bold.)

The fast new computer could beat the old one any day.
In this case, "fast" and "new" are adjectives modifying the noun "computer", and "old" modifies the pronoun "one".
The plane was loud.
In this case, "loud" is working as predicate adjective, describing the subject, "plane".


Adverb

Adverbs modify adjectives, other adverbs, or verbs. They modify verbs most often. When modifying adjectives and adverbs, adverbs cannot move and therefore are fairly easy to spot. When modifying a verb, adverbs answer "when", "where", "how", "why", "how often" and similar questions (Lester and Beason 14). For tips on identifying what an adverb is modifying, look at the "Tips & Tricks" section.

Example(The adverbs are bold, the words they modify are underlined.)

The ridiculously boring television show ended at eight.
"Ridiculously" is modifying the adjective "boring".
The instructor responded to the e-mail quite quickly.
In this sentence, "quite" is modifying the adverb "quickly" while "quickly" modifies the verb "responded". Students use the library frequently.
The question posed here is "how often do students use the library", and the answer is "frequently". That means the adverb "frequently" modifies the verb "use".


Conjunction

Conjunctions join words or phrases. There are two types: coordinating conjunctions that join equal parts, and subordinating conjunctions that join unequal phrases. FANBOYS is useful to remember, because it combines the main coordinating conjunctions "for", "and", "nor", "but", "or", "yet", and "so".

Example(The conjunctions are bold, the words they join are underlined.)

Peter likes to run and to play baseball.
"And" is used to join equal infinitive verbs. This is a coordinating conjunction because neither phrase is more important than the other.
Peter likes to swim after he runs.
"Peter likes to swim" is an independent clause and carries more weight than the dependent clause "after he runs". "After" is the subordinate conjunction in this sentence.


Interjection

Interjections are words placed into sentences for emphasis. If removed, the sentence still makes sense and is grammatically correct because interjections are not required (Lester and Beason 311). They may or may not be followed by exclamation marks.

Example(The interjection is bold.)

Well, I think I'll go to the store.
If the "well" is removed from this sentence, it still make sense.


Noun

Nouns are the names of people, places, things, and ideas. There are two types of nouns: proper nouns, which are names of specific people, places, or things, and common nouns which are the general names of people, places, things, ideas (Lester and Beason 4). Nouns are a part of the subject of a sentence.

Example(The nouns are bold.)

John got the cat out of the tree.
"John" is the name of a specific person and therefore is a proper noun. "Cat" and "tree" are the names of things, but not a specific thing, so they are common nouns.


Preposition

Prepositions are words that begin prepositional phrases. They are bound to an object (either a noun or pronoun) in the phrase (Lester and Beason 21). For more information on prepositional phrases, look at the "Phrases" tab.

Example(The preposition is bold and the object is underlined.)

This book of safety rules is very heavy.
"Of safety rules" is a prepositional phrase that helps clarify which book is being indicated.


Pronoun

Pronouns take the place of or represent a noun and must agree with the number and gender of the noun. There are four types of pronouns, and they have different persons. To make it easier to understand, each of the types is broken down below.

Personal pronouns

Personal pronouns take the place of nouns. There are three persons: first-person (the speaker), second-person (the hearer), and-third person (neither the speaker nor the hearer). The choice of pronoun depends on which person the noun is, the gender, and the number, and whether the noun was acting as a subject in a sentence, an object of a preposition or a verb, or as possessive of something else. Fortunately, there is list of personal pronouns that can help make it easier to understand.

First-Person
Function Singular Plural
Subject I we
Object me us
Possessive mine ours
Second-Person
Function Singular Plural
Subject you you
Object you you
Possessive yours yours
Third-Person
Function Singular Plural
Subject he, she, it they
Object him, her, it them
Possessive his, hers, its theirs

Reflexive Pronoun

Reflexive pronouns must refer to a noun or pronoun in the same sentence. All reflexive pronouns end with -self or -selves (Lester and Beason 18). Like personal pronouns, these are broken into first-, second-, and third-person. These do not, however, get broken into functions.

Person Singular Plural
First-person myself ourselves
Second-person yourself yourselves
Third-person himself, herself, itself themselves

Indefinite Pronouns

Indefinite pronouns talk about unknown amounts of persons or things (Lester and Beason 18). These pronouns do not reflect gender or person. Many of these pronouns begin with "any", "every", "no", and "some" and end with "-body", "-one", or "-thing".

Demonstrative Pronouns

Demonstrative pronouns help show or point out the thing being talked about in the sentence. There are only four pronouns that play this role: "this", "that", "these", and "those". Note: all four of these words can be used as adjectives, so check to make sure that the pronoun is not modifying anything.

Example(The pronoun is bold and the noun it refers to is underlined.)

That guitar is hers.
"Hers" is a possessive, third-person pronoun replacing the name of the girl who owns the guitar.
Stephanie bought the guitar for herself.
"Herself" is a reflexive pronoun reflecting "Stephanie".
Few play the guitar as well as Stephanie.
"Few" refers to a group of people, but the amount and gender are unknown.
Can you play that?
"You" is a second-person pronoun that makes the subject of the sentence. "That" is a demonstrative pronoun that stands on its own to point out some object; usually, the sentences before or after explain what the object is.


Verb

Verbs show action or describe states of being. Action verbs show action while linking verbs describe states of being (Lester and Beason 6). Linking verbs are sometimes identical to action verbs, but the difference comes in whether or not the subject of the sentence is committing an action. Verbs show a tense because actions and states of being can change from minute to minute or day-to-day, or they can be anticipated. To learn more about verbs, visit the "Verbs & Verbals" tab.

Example(The verb is bold.)

Tom called Jim on his new phone.
"Called" is a verb expressing action. The subject did something.
The phone was green.
"Was" is a verb expressing a state of being. A phone cannot do green. Instead, it is being described as green.

Phrases

What are Phrases?

Phrases are groups of words that work together as a single part of speech (Lester and Beason 321). There is usually a head, which is a noun, verb, adjective, or preposition, combined with its modifiers and objects. There are many types of phrases and the most common kinds are listed below.

Appositive Phrases

Appositive phrases are noun phrases that help to rename or identify a noun (Lester and Beason 300). Typically it is the noun before the phrase. They can be either essential or non-essential. Essential appositive phrases are necessary to identify the noun it modifies. Nonessential appositives are not.

Example(Appositive phrase is bold, the noun it modifies is underlined.)

That book, the one with the blue cover, is a good one.
Without the appositive phrase "the one with the blue cover", there would be no way of knowing which book is good.
Timothy's mother, a doctor, reads every day.
The appositive phrase "a doctor" is not important to this sentence. We know whose mother is being referred to, and her profession is not important to whether or not she reads.


Gerund Phrases

Gerunds are verbs that are used as nouns. A gerund phrase acts as a noun and can be the subject of a sentence (Lester and Beason 309).

Example(Gerund is bold, gerund phrase is underlined.)

Eating too much food at once can be an unpleasant experience.
The gerund phrase is the subject of the sentence. The verb is "can be" and it is describing a state of being after having eaten too much.


Infinitive Phrases

Infinitives are verbs with "to" in front of them and before they are changed in tense (Lester and Beason 311). Infinitive phrases act as nouns, adjectives, and adverbs.

Example(The infinitive is bold and the infinitive phrases are underlined.)

The doctor wanted to send his patient to a specialist.
The infinitive phrase is taking the place as the object of the verb "wanted".


Noun Phrases

Noun phrases are nouns with modifiers that act as nouns. Technically, infinitive phrases and gerund phrases that are used as nouns are also considered noun phrases (Lester and Beason 316).

Example(The noun is bold and the noun phrase is underlined.)

The big, black clouds hurried across the sky.
"Cloud" is the noun, and "big, black" are adjectives modifying the noun. All together, they act as the subject for the verb.


Prepositional Phrases

Prepositional phrases act as either adjectives or adverbs. When acting as adjectives, the prepositional phrases modify nouns. When acting as adverbs, they modify verbs.

Example(The prepositional phrase is bold and the word being modified is underlined.)

The house in the woods is very old.
In this case, the prepositional phrase is acting as an adjective, modifying the noun.
We went in the woods to find the house.
The prepositional phrase "in the woods" in this case is acting as an adverb by saying where the subject went.

Tips & Tricks

Miscellaneous Tips and Tricks

  • The "To/For" Test: indirect objects can be determined by adding "to" or "for" in front of the phrase. Then it must be moved to the back of the direct object (Lester and Beason 34).
  • Third-Person Pronouns: To determine whether a clause is an adjective clause, and to find the noun it modifies, replace the noun and the clause with third-person pronoun. If it is still grammatical and makes sense, then the clause modifies that noun and is an adjective clause (Lester and Beason 56).
  • Another "It" Test: To find a gerund phrase, look for the present participle and replace it with "it". If it makes sense, the phrase is a gerund phrase.
  • Pronoun Replacement Test: To identify a participial phrase and the noun it modifies, replace a noun and the phrase that has the participle in it with a single pronoun. If it makes sense, then it is a participial phrase (Lester and Beason 101).
  • Tip: "Part of speech is determined by function. When nouns and pronouns are used in their possessive forms, they are functioning as adjectives and are no longer classified as nouns and pronouns." (Lester and Beason 10). This is also true of verb phrases acting as nouns.

Examples

The bank gave the family a loan.
This sentence would still make sense if it was written as "The bank gave a loan to the family." "The family" is an indirect object that is made into a prepositional phrase and then moved behind the direct object.
The fireman, who had years of experience, allowed everyone back into the building. "The fireman, who had years of experience" can be replaced by the third-person pronoun "he". "He allowed everyone back into the building" is still correct and it still makes sense.
Running around at the park made the children tired.
Replacing the participial phrase "Running around at the park" with "it" means the sentence is still grammatically correct: "It made the children tired".
Following the car in front of me, I soon grew tired of the quick lane changes. Replacing "following the car in front of me, I" with "he" changes the meaning of the sentence, but it is still grammatically correct. "He soon grew tired of the quick lane changes" is still a correct sentence, so "following the car in front of me" is a participial phrase that modifies "I".


Tips and Tricks for Adjectives

  • The Pairing Test: If a word that modifies can be paired with a noun and make sense, then it is an adjective (Lester and Beason 8).

Example(The adjective is bold and the word being modified is underlined.)

The truck is red.
To determine that "red" really is an adjective, simply place "red" in front of "truck". "The red truck" makes sense, so it is an adjective.


Tips and Tricks for Adverbs

  • The Question Test: if a word or clause answers the questions "when", "where", "why", "how", and "how often", it is an adverb or adverb clause that modifies the verb rather than another adverb or an adjective (Lester and Beason 12).
  • The Movement Test: if a modifying word or clause can be moved within a sentence and still make sense, it is an adverb that modifes a verb (Lester and Beason 13).

Examples(The adverb clause is underlined and the word it modifies is bold.)

The boys ran after they got home from school.
"After they got home from school" modifies "ran" because it answers the question: "when did the boys run?"
After they got home from school , the boys ran.
This is the same sentence as the previous example, but the adverb phrase was able to move to the front and still make sense, so it modifies the verb. Adverbs that modify adjectives and other adverbs can only be placed directly after the word or phrase being modified.


Tips and Tricks for Agreement

  • Lost Subjects: If the subject of a sentence is hard to find, locate the verb and then move to the left, looking for the first noun that is not part of an introductory phrase. Then, test the noun for subject-verb agreement (Lester and Beason 126).
  • Existential There: If a sentence includes an existential there (there is, there are) check the noun closest to the linking verb. That is the noun to check for subject-verb agreement with (Lester and Beason 132).
  • Pronoun Replacement: when "and" joins compound subjects, replace the entire subject with "they" or "it". If "it" is correct, then it is singular. "They" is more common and take a plural verb (Lester and Beason 137).

Example(The subject is bold and the verb is underlined.)

George R.R. Martin, the author of the Song of Fire and Ice series, which includes dragons and magic, has written several novels with various topics like aliens, vampires, and the end of the world.
The example sentence is confusing, but using the verb phrase, "has written", as a starting point and moving backwards to look for nouns, it is clear that "dragons" and "magic" don't work, because they modify "The Song of Fire and Ice series", which is a prepositional phrase modifying "author". Author is close, but by going back one further, it helps to define who "George R.R. Martin" is. That name does not modify anything, and when tested with "has written" for agreement, it agrees.
There are two dogs running around outside.
"There are" is a verb phrase that merely points out the existence of something, there is no action happening. For the helping verb "to be" to agree with a plural subject the correct form is "are".
John and Kathy are trying to catch their dogs.
"John and Kathy" can be replaced easily by "they". "They are trying to catch their dogs" still makes perfect sense, while "It are trying to catch their dogs" does not.


Tips and Tricks for Nouns

  • The "The" Test for Common Nouns: to figure out if a word is a common noun, try to place "the" immediately in front of it. If it makes sense, it is a common noun (Lester and Beason 5).
  • The "It" Test for Noun Clauses: to figure out if a clause is a noun clause, try to replace the entire clause with "it". If it makes sense, it is a noun clause (Lester and Beason 62).

Examples

Trees are places for cats to hide.
There are three common nouns in this sentence. By using "the" in front of trees, we see the sentence still makes sense. If you place "the" in front of "are", the sentence no longer makes sense. The other two common nouns are "(the) places" and "(the) cats".
The boy played the game very well. The sentence would still be grammatically correct and make sense if it were "the boy played it." Context would have to explain what "it" was, though.


Tips and Tricks for Pronouns

  • Subject versus Object Forms: The subject form of a pronoun is what would fill in the blank in a sentence such as "________ worked." The object form of a pronoun is what would fill in the blank in a sentence such as "The work was given to ________."
  • Him versus Whom: Him and whom are both object pronouns. If you used "him" instead of "whom", and the sentence still makes sense, then "whom" is correct, not "who" (Lester and Beason 150).
  • Compounds with Pronouns: if a compound has two pronouns or a noun and a pronoun, re-arrange the sentence to just use the pronoun. If it makes sense, then the right form is being used; if it does not, then choose a different pronoun (Lester and Beason 147).

Examples

He worked because the work was given to him.
This sample combines both of the test sentences. "He" is the subject form, and "him" is the object form. In that simple sentence, both are used correctly.
Who worked? The work was given to whom?
"Who" is subject case while "whom" is object case. The two questions in that example are just question versions of the previous example. It would be appropriate to replace "whom" with "him" and the question would still be grammatically correct: "The work was given to him?"
You and I should go to the store tomorrow.
Compounds that involve pronouns can be confusing. "You and I" versus "you and me" can be very difficult to figure out. In the sample sentence, "I should go to the store" makes sense, so "I" is the correct pronoun. "Me should go to the store" would be incorrect. This works in many different situations, whether the compound is part of the subject or part of the object.


Tips and Tricks for Verbs

  • The "Will" Test: if "will" is placed in front of another word and the phrase makes senses, then the word being tested must be a verb (Lester and Beason 7). Note: the tense of the test word may need to be changed.

Example

The book sat on the shelf.
The base of "sat" is "sit". If "will" is placed in front of "sit", the sentence still makes sense.

Verbs & Verbals

What are verbs?

Verbs show action or describe states of being. Action verbs show action while linking verbs describe states of being (Lester and Beason 6). Linking verbs are sometimes identical to action verbs, but the difference comes in whether or not the subject of the sentence is committing an action. Verbs show a tense because actions and states of being can change from minute to minute or day-to-day, or they can be anticipated.

Verb Forms

There are several types of verb forms, and most have their own rules. Here's a brief description of the rule and how the form is created. There are a few examples at the bottom.

Base Form

The base form of the verb is the verb that all of the other forms are based on. This includes words like "be", "walk", "run", "talk," and etc. The base form is used primarily in commands (imperative sentences), and in future tense. The base form is also used for the present form in many cases. To make a verb future tense, simply add "will" before the base (Lester and Beason 74).

Present Form

The present form is either the base form, for first-person and second-person singular and plural, and third-person plural, or the base form plus an "s" at the end for third-person singular. This is true for almost all forms, though "be" is an exception (Lester and Beason 75).

Past Form

The past form is more complicated. Most verbs can be made past form by adding "d" or "ed" to the end; however, many verbs are irregular and cannot follow the normal pattern for past form. These verbs often have a single vowel changed. Some verb forms simply have to be memorized, such as the forms for "be" and for "go" (Lester and Beason 76).

Infinitive Form

The infinitive form is the same for all verbs, making it easy to remember and to use. It is "to" plus the base form. Infinitive verbs can be used to make infinitive phrases which act as nouns, adjectives, or adverbs (Lester and Beason 77).

Present Participle Form

The present participle form is the same for all verbs. Simply add "ing" onto the end of the verb. Present participle forms can be used in gerunds and gerund phrases which then act as nouns (Lester and Beason 77).

Past Participle Form

Like past form verbs, past participle verbs are often formed the same way: by adding "ed" or "d" to the end of the verb. The words that are irregular in past are irregular in past particple as well, but the vowel being changed is changed once more. To make a past tense verb into a past participle, a form of "have" or "be" must be before the verb (Lester and Beason 78).


Regular Verbs
Base Form Present Form Past Form Infinitive Form Present Participle Form Past Participle Form
Talk talk talk, talks talked to talk talking talked
Smile smile smile, smiles smiled to smile smiling smiled
Irregular Verbs
Base Form Present Form Past Form Infinitive Form Present Participle Form Past Participle Form
Sing sing sing, sings sang to sing singing sung
Write write write, writes wrote to write writing written
Be
Base Form Present Form Past Form Infinitive Form Present Participle Form Past Participle Form
be be is, are was, were to be being been
Go
Base Form Present Form Past Form Infinitive Form Present Participle Form Past Participle Form
Go go go, goes went to go going gone

Examples

Smile, people are watching.
"Smile" is in its base form in this example, since it is an imperative sentence, telling the reader to smile.
I smile as often as I can, but he never smiles.
"I" is first-person, so it takes the base form; "he" is third-person singular, so it takes the base+s form, "smiles".
We all smiled for that picture.
The picture was taken in the past, so "smiled" in the past form is used.
You need to smile.
"Need" is the verb in this sentence, and "to smile" is an infinitve phrase working as a direct object.
Smiling is good for the heart.
"Smiling" is a present participle form working as a gerund in this sentence, it is acting as a noun.
He had smiled only once in his life.
"Smiled" comes after the helping verb "had" in this sentence and is therefore a past participle rather than a past form.


Modal Verbs

Modal verbs are five verbs that have only two forms: present and past. These verbs can only be used with another verb in its base form (Lester and Beason 79). They are as follows:

Modal Verbs
Present Form Past Form
can could
may might
must ----
shall should
will would

Verb Tenses

Verb tenses put the above forms into proper use so that sentences tell a story and make sense. There are six tenses total, with two categories: simple and perfect. Each category has present, past, and future tenses (Lester and Beason 80).

Present Tense

The present tense does not describe activities happening in that instant. Instead, it is used to state facts and to make generalizations. Present tense is created simply by having the present form of the verb, making sure it agrees in person if the subject is third-person singular.

Examples(Verb is bold.)

August is hot in Georiga.
"August" is not performing an activity, and it is certainly not performing an activity right in that instant. Instead, the sentence and its present tense verb "is" is simply stating a fact.
Dogs smell strange.
The "Dogs" aren't smelling strange. Instead, "smell" in this case is a generalization, suggesting that most or all dogs have a strange smell.

Past Tense

Past tense describes activities that happened in the past. Additionally, because present tense is not used for things happening in the present, writing that is recording events is written in the past tense (Lester and Beason 83). Past tense simply uses the past form in a sentence.

Example(Verb is bold.)

John grabbed the paper from the table.
A single action happened in the past, so the past form is used to make the sentence past tense.

Future Tense

Future tense describes activities that will happen or might happen in the future. These are created by using a modal verb and then the base form of the main verb to create a verb phrase. "Will" is the most common modal verb used in the future tense (Lester and Beason 83).

Example(Verb is bold.)

Tomorrow, we will arrive at school on time.
"Will arrive" is the future tense verb in this sentence.

Present Perfect Tense

Present perfect tense is created by adding the helping verbs "have" or "has" plus the past participle form of the main verb. The tense describes activities that have happened in the past over a period of time and have either ended very recently, or are expected to continue into the future (Lester and Beason 84).

Examples(Helping verb is underlined, past participle is bold.)

That machine has been on all morning.
In the example, the machine started working in the morning, and continued working throughout the morning. It has either just stopped, or more likely, is still on and may continue being on.

Past Perfect Tense

Past perfect tense is formed by taking "had" and the past participle. It describes an event that happened in the past and was already completed before something else happened. It is often used to give a timeline or a sequence of events (Lester and Beason 85).

Example(Helping verb is underlined, past participle is bold.)

He had gotten into the car when he realized the keys were still inside the house.
The driver was already in the car, that action was completed. Then, he realizes that he does not have the keys.

Future Perfect Tense

Future perfect tense is created by having "will have" in front of the past participle form of a verb. It represents an action that has not happened yet, but is going to happen and will be completed by a certain time (Lester and Beason 86).

Example(Helping verb is underlined, past particple is bold.)

Fall semester classes at GNTC will have ended by Christmas.
The Fall classes are not yet over in this sentence, but they will be over before it becomes Christmas.

Progressive Forms

Progressive verbs are tenses that are neither simple nor perfect; however, as with simple and perfect, there are three tenses: present, past, and future (Lester and Beason 87).

Present Progressive

Present progressive is used for activities that are occuring right at that moment. It uses the present tense of "be" plus the present participle of the verb (Lester and Beason 87).

Example(The helping verb is underlined, the main verb is bold.)

I am writing this guide with the help of a book.
The book is being used at the very moment of writing the guide.

Past Progressive

Past progressive is used for activities that were in progress in the past, but have since been completed. It uses the past tense of "be" plus the present participle (Lester and Beason 88).

Example(The helping verb is underlined, the main verb is bold.)

John was riding his bicycle when the car cut him off.
John was still in the progress of riding his bicycle when he interacted with the car. Now, though, that action is over and done with.

Future Progressive

Future progressive is used for actions that will be in progress in the future. It uses "will be" plus the present participle form of a verb.

Example(The helping verb is underlined, the main verb is bold.)

By the time we get there, class will be ending!
The class is not over yet, but by the time the first part of the sentence has happened, the second part will be happening.


Passive and Active Voice

There are two "voices" for verbs. Passive voice has an action happening to someone or something. In active voice, someone or something is doing the action. Passive sentences always have some form of the verb "be" in them.

Examples

The clothes were washed by Andrew.
This example is passive. "Were" is the form of the "be" verb, and the clothes cannot be doing the action of washing. Rather, they had washing happening to them, done by Andrew.
Andrew washed the clothes.
This is the same sentence and has pretty much the same meaning, but it uses fewer words. Andrew is doing the action of washing the clothing.


What are Verbals?

Verbals are verb forms being used as nouns, adjectives, or adverbs(Lester and Beason 332). These each have their own names and will be looked at below.

Verbal Forms

Verbals can be gerunds, participles, or infinitives. Each type of phrase is discussed under "Phrases", but the type, form, and part of speech are shown below (Lester and Beason 95). For examples, please look at the "Phrases" tab.

Type Form Part of Speech
Gerund Phrase Present Participle Noun
Participial Phrase Present OR Past Participle Adjective
