Definition of “Is,” “Am,” and “Are”

“Is,” “am,” and “are” are forms of the verb “to be,” one of the most common and essential verbs in the English language. They are primarily used as linking verbs, connecting the subject of a sentence to a noun or adjective that describes or identifies it.

They can also function as auxiliary verbs, helping to form continuous (progressive) tenses.

Classification and Function

As linking verbs, “is,” “am,” and “are” do not express an action. Instead, they describe a state of being or a condition.

They link the subject to a subject complement, which can be a noun, pronoun, or adjective. When used as auxiliary verbs, they combine with a present participle (verb ending in “-ing”) to form continuous tenses, indicating an ongoing action.

Contexts of Usage

These verb forms are used in a wide range of contexts, including:

  • Describing people, places, and things
  • Expressing feelings and emotions
  • Stating facts and opinions
  • Forming questions
  • Indicating present continuous actions

Structural Breakdown

The correct usage of “is,” “am,” and “are” depends on the subject of the sentence. Each verb form corresponds to specific pronouns and noun types, as described below:

  • Am: Used with the first-person singular pronoun “I.”
  • Is: Used with third-person singular pronouns (he, she, it) and singular nouns.
  • Are: Used with first-person plural pronoun “we,” second-person pronouns (you, both singular and plural), third-person plural pronoun “they” and plural nouns.

Subject-Verb Agreement

The most crucial rule is subject-verb agreement. The verb must agree in number (singular or plural) with its subject.

This means that a singular subject takes a singular verb (“is” or “am”), while a plural subject takes a plural verb (“are”).

Here’s a table illustrating the basic subject-verb agreement:

Subject Verb Form Example
I Am I am a student.
He, She, It, Singular Noun Is He is tall. The book is interesting.
We, You, They, Plural Noun Are We are friends. You are kind. The books are heavy.

Types and Categories of Usage

“Is,” “am,” and “are” can be used in various sentence structures and tenses. Here’s a breakdown of the main categories:

1. Simple Present Tense (Stating Facts or General Truths)

In the simple present tense, these verbs express a current state or a general truth. They are used to describe who or what someone or something is.

2. Present Continuous Tense (Describing Ongoing Actions)

In the present continuous tense, “is,” “am,” and “are” are used as auxiliary verbs to indicate an action that is happening now or around the present time. The present continuous tense is formed by combining “is/am/are” with the present participle (verb + -ing).

3. Describing Qualities or Characteristics

These verbs are used to describe the qualities, characteristics, or attributes of a person, place, or thing. They connect the subject to an adjective that provides more information about it.

4. Expressing Location

“Is,” “am,” and “are” can indicate the location of someone or something. This often involves using prepositions of place (e.g., in, on, at, under, near).

5. Forming Questions

To form questions, “is,” “am,” and “are” are typically placed before the subject of the sentence. This is known as subject-verb inversion.

6. Negative Sentences

To form negative sentences, “not” is added after “is,” “am,” or “are.” Contractions like “isn’t,” “aren’t,” and “I’m not” are commonly used.

Usage Rules

Here are the key rules governing the proper use of “is,” “am,” and “are”:

  • Subject-Verb Agreement: The verb must agree in number with the subject.
  • Pronoun Agreement: Use “am” with “I,” “is” with “he,” “she,” and “it,” and “are” with “we,” “you,” and “they.”
  • Singular vs. Plural Nouns: Use “is” with singular nouns and “are” with plural nouns.
  • Collective Nouns: Collective nouns (e.g., team, family, committee) can be singular or plural depending on whether they are acting as a unit or as individual members. If the collective noun is acting as a single unit, use “is.” If the members are acting individually, use “are.” For example: “The team is playing well.” (acting as a unit) vs. “The team are arguing among themselves.” (acting individually).
  • Compound Subjects: When two or more subjects are joined by “and,” use “are.” However, if the subjects refer to the same person or thing, use “is.” For example: “John and Mary are coming to the party.” vs. “My friend and colleague is arriving tomorrow.”
  • Indefinite Pronouns: Some indefinite pronouns (e.g., each, everyone, somebody) are singular and take “is.” Others (e.g., several, both, few) are plural and take “are.” For example: “Everyone is welcome.” vs. “Few are interested in the topic.”

Advanced Topics

For advanced learners, here are some more complex aspects of using “is,” “am,” and “are”:

1. Subject-Verb Agreement with “There Is/There Are”

When using “there is/there are,” the verb agrees with the noun that follows it. If the noun is singular, use “there is.” If the noun is plural, use “there are.” For example: “There is a book on the table.” vs. “There are books on the table.”

2. Subject-Verb Agreement with “Either/Or” and “Neither/Nor”

When subjects are joined by “either/or” or “neither/nor,” the verb agrees with the subject that is closest to it. For example: “Either John or Mary is going to the meeting.” vs. “Neither the students nor the teacher is present.”

3. Using “Is,” “Am,” and “Are” in Subjunctive Mood

In subjunctive mood, “were” is often used instead of “was” or “is” to express hypothetical or contrary-to-fact situations, regardless of the subject’s number. This is most common in “if” clauses and after verbs like “wish” and “suggest.” For example: “If I were you, I would take the job.”

Frequently Asked Questions (FAQ)

Here are some frequently asked questions about the usage of “is,” “am,” and “are”:

  1. Q: When do I use “am” instead of “is” or “are”?

    A: You use “am” exclusively with the first-person singular pronoun “I.” For instance, “I am a teacher,” or “I am going to the store.” This is a fixed rule in English grammar.

  2. Q: How do I know when to use “is” versus “are”?

    A: “Is” is used with third-person singular pronouns (he, she, it) and singular nouns. “Are” is used with first-person plural pronoun “we,” second-person pronouns (you, both singular and plural), third-person plural pronoun “they,” and plural nouns. Remember to always ensure the verb agrees with the subject in number.

  3. Q: What is the difference between “there is” and “there are”?

    A: “There is” is used when referring to a singular noun, while “there are” is used when referring to a plural noun. For example, “There is a cat on the roof” (singular) versus “There are cats on the roof” (plural). The verb agrees with the noun that follows it.

  4. Q: Can collective nouns be used with “is” and “are”?

    A: Yes, collective nouns (like “team,” “family,” “committee”) can be used with both “is” and “are,” depending on whether the collective noun is acting as a single unit or as individual members. If the collective noun is acting as a single unit, use “is.” If the members are acting individually, use “are.” For example: “The team is playing well” (unit) vs. “The team are arguing among themselves” (individuals).

  5. Q: How do I form negative sentences with “is,” “am,” and “are”?

    A: To form negative sentences, add “not” after “is,” “am,” or “are.” Contractions like “isn’t,” “aren’t,” and “I’m not” are commonly used. For example: “He is not a student” or “He isn’t a student.”

  6. Q: How do I form questions with “is,” “am,” and “are”?

    A: To form questions, place “is,” “am,” or “are” before the subject of the sentence. For example: “Are you coming to the party?” or “Is she a doctor?” This is known as subject-verb inversion.

  7. Q: What is the present continuous tense, and how do “is,” “am,” and “are” fit in?

    A: The present continuous tense describes an action that is happening now or around the present time. It is formed by combining “is,” “am,” or “are” with the present participle (verb + -ing). For example: “I am studying,” “He is working,” or “They are playing.”

  8. Q: What are some common mistakes to avoid when using “is,” “am,” and “are”?

    A: Common mistakes include using “is” with plural subjects (e.g., “The books is on the table”) or using the wrong verb form with pronouns (e.g., “I is happy”). Always double-check subject-verb agreement to avoid these errors.
