Definition of ‘Is,’ ‘Am,’ and ‘Are’

“Is,” “am,” and “are” are all forms of the verb “to be,” one of the most fundamental and frequently used verbs in the English language. They are primarily used in the present tense and serve several crucial grammatical functions. As forms of “to be,” they are linking verbs, connecting the subject of a sentence to a noun or adjective that describes or identifies it. They can also act as auxiliary verbs, helping to form continuous (progressive) tenses.

Specifically:

• Am is used with the first-person singular pronoun I.
• 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, whether singular or plural), third-person plural pronouns (they), and plural nouns.

Understanding the use of “is,” “am,” and “are” goes beyond simple subject-verb agreement. These verbs serve as both linking verbs and auxiliary verbs, providing clarity and precision in sentences. The correct use of “is” links singular third-person subjects to their complements, “am” pairs with the first-person singular pronoun, and “are” connects plural subjects or the pronoun “you” to the appropriate complement. Mastering these uses ensures that both written and spoken English convey meaning accurately and naturally.

Are “Is,” “Am,” and “Are” Verbs?

“Is,” “am,” and “are” are verbs, specifically forms of the verb “to be.” As verbs, they perform two key functions. First, as linking verbs, they connect the subject to a noun or adjective that describes it—for example, “She is a teacher,” where “is” links “she” to “teacher.” Second, as auxiliary verbs, they help form continuous tenses, such as “I am reading” or “They are studying.” Recognizing these words as verbs is essential for understanding sentence structure and expressing actions, states, or characteristics accurately.

In essence, “is,” “am,” and “are” indicate a state of being, an identity, a characteristic, or an ongoing action in the present. They are essential for constructing simple yet meaningful sentences.

Structural Breakdown

The structure of sentences using “is,” “am,” and “are” typically follows a Subject-Verb-Complement (SVC) pattern, especially when functioning as linking verbs. The subject is what or whom the sentence is about.

The verb (“is,” “am,” or “are”) connects the subject to the complement, which provides additional information about the subject. When used as auxiliary verbs, they combine with a present participle (verb ending in -ing) to form continuous tenses, indicating an ongoing action.

Here are the basic structural patterns:

• Subject + Am + Complement: I am happy.
• Subject + Is + Complement: He is a doctor.
• Subject + Are + Complement: They are students.
• Subject + Am + Verb-ing: I am studying.
• Subject + Is + Verb-ing: She is singing.
• Subject + Are + Verb-ing: We are learning.

Understanding these patterns helps in constructing grammatically correct and meaningful sentences. The correct form of “to be” depends entirely on the subject of the sentence.

Categories of Use

“Is,” “am,” and “are” can be categorized based on their function within a sentence. The primary categories are:

Linking Verbs

As linking verbs, “is,” “am,” and “are” connect the subject to a noun or adjective that describes or identifies the subject. The complement renames or describes the subject.

This usage emphasizes a state of being or a characteristic.

Auxiliary Verbs (Helping Verbs)

As auxiliary verbs, they combine with a present participle (verb ending in -ing) to form the present continuous (or progressive) tense. This usage indicates an action that is currently in progress.

Existential ‘There’

In sentences beginning with “There,” “is” and “are” indicate the existence of something. The choice between “is” and “are” depends on the noun that follows the verb.

Usage Rules

The correct usage of “is,” “am,” and “are” is governed by subject-verb agreement. The rules governing “am,” “is,” and “are” are straightforward once subject-verb agreement is understood. Simply put, “am” is always used with “I,” “is” with singular third-person subjects, and “are” with plural subjects and “you.” These basic am is are rules are crucial for forming correct sentences and avoiding frequent errors.

This means that the verb form must agree in number (singular or plural) with the subject of the sentence.

Understanding and applying this rule is crucial for grammatical accuracy.

Subject-Verb Agreement

The basic rule of subject-verb agreement is as follows:

• Singular subjects take singular verbs (is).
• Plural subjects take plural verbs (are).
• The pronoun “I” takes “am.”
• The pronoun “you” takes “are,” regardless of whether it is singular or plural.

Examples:

• The dog is barking. (Singular subject, singular verb)
• The dogs are barking. (Plural subject, plural verb)
• I am a student. (Pronoun “I,” verb “am”)
• You are my friend. (Pronoun “you,” verb “are”)

Exceptions to the Rules

While subject-verb agreement is generally straightforward, there are some exceptions and special cases to consider:

• Collective nouns: Collective nouns (e.g., team, family, committee) can be singular or plural depending on whether they are acting as a single unit or as individual members.
  • The team is playing well. (Team as a unit)
  • The team are arguing about the strategy. (Team as individual members)
• Indefinite pronouns: Some indefinite pronouns (e.g., each, every, someone, nobody) are always singular, while others (e.g., several, both, few) are always plural.
  • Each student is responsible for their own work.
  • Several students are absent today.
• Compound subjects: Subjects joined by “and” are usually plural unless they refer to the same person or thing.
  • John and Mary are coming to the party.
  • The author and editor is arriving soon. (Same person)

Special Cases

Some special cases require careful attention to subject-verb agreement:

• Sentences starting with “Here” or “There”: In these sentences, the subject follows the verb.
  • Here is the book you wanted.
  • There are many reasons to be happy.
• Titles of books, movies, and songs: Titles are generally treated as singular even if they contain plural nouns.
  • “The Adventures of Tom Sawyer” is a classic novel.
• Words used as words: When a word is referred to as a word, it is treated as singular.
  • “Data” is often used as a singular noun, though it is technically plural.

Advanced Topics

For advanced learners, understanding the nuances of “is,” “am,” and “are” in more complex grammatical structures can further enhance their proficiency.

Subjunctive Mood

The subjunctive mood is used to express wishes, suggestions, or hypothetical situations. In some cases, the verb “to be” takes the form “were” regardless of the subject.

This is most commonly seen in “if” clauses expressing unreal conditions.

Example:

• If I were you, I would take the job. (Instead of “If I was you…”)

Inverted Sentences

Inverted sentences occur when the verb comes before the subject. This is often seen in questions or sentences beginning with certain adverbs.

Subject-verb agreement remains crucial in inverted sentences.

Examples:

• Is he coming to the party? (Instead of “He is coming to the party?”)
• Here are the keys. (Instead of “The keys are here.”)

FAQ

Here are some frequently asked questions about the use of “is,” “am,” and “are.”

Q: When do I use “is” versus “are”?

A: “Is” is used with singular subjects (e.g., he, she, it, the dog), while “are” is used with plural subjects (e.g., we, you, they, the dogs).

Q: Why do we use “are” with “you” even when it’s singular?

A: The pronoun “you” historically takes the plural form of the verb “to be” regardless of whether it refers to one person or multiple people. This is a grammatical convention in English.

Q: How do I know if a collective noun is singular or plural?

A: If the collective noun is acting as a single unit, use a singular verb (is). If the members of the collective noun

are acting individually, use a plural verb (are). Context is key.

Q: What about sentences that begin with “there”?

A: In sentences that begin with “there,” the verb (“is” or “are”) agrees with the noun that follows the verb. For example, “There is a cat” (singular) versus “There are cats” (plural).

Q: Can “is,” “am,” and “are” be contracted?

A: Yes, these verbs can be contracted, especially in informal writing and speech. For example, “I am” can be contracted to “I’m,” “he is” to “he’s,” and “they are” to “they’re.”
