Is Versus Are In A Sentence

Understanding the difference between is and are in a sentence is essential for mastering English grammar, as these two forms of the verb to be dictate subject‑verb agreement and affect clarity. Choosing the correct form helps speakers and writers convey meaning accurately, avoid awkward constructions, and sound more professional in both spoken and written communication. This guide breaks down the rules, highlights common pitfalls, and offers practical tips so you can confidently decide whether to use is or are in any sentence.

Introduction to Subject‑Verb Agreement

At its core, the choice between is and are depends on whether the subject of the sentence is singular or plural. In real terms, the verb to be must match the number (singular/plural) and person (first, second, third) of its subject. When the subject is a single entity—whether a noun, pronoun, or clause—is is the appropriate form. In real terms, when the subject consists of more than one entity, are takes its place. While this sounds straightforward, English contains many nouns and pronouns that behave unexpectedly, making it worthwhile to examine each category in detail.

When to Use Is

Use is when the subject is singular. This includes:

• Singular nouns: The cat is sleeping.
• Singular pronouns: He is ready. / She is late. / It is raining.
• Uncountable nouns: Water is essential for life. / Information is power.
• Collective nouns treated as a unit: The team is winning. / The committee has decided.
• Indefinite pronouns that are singular: Someone is at the door. / Everybody enjoys the show. / Nothing is impossible.
• Gerund phrases acting as a subject: Running is good exercise.
• Infinitives as subjects: To err is human.
• Clauses functioning as a singular subject: What she said is true.

Special Singular Cases

Certain words that end in -s or look plural are actually singular and therefore take is:

• News: The news is surprising.
• Mathematics, physics, economics (when referring to the field): Mathematics is challenging.
• Measles, mumps, etc. (diseases): Measles is contagious.

When to Use Are

Use are when the subject is plural. This covers:

• Plural nouns: The dogs are barking.
• Plural pronouns: We are excited. / You are welcome. / They are late.
• Compound subjects joined by and: Tom and Jerry are friends.
• Indefinite pronouns that are plural: Few are chosen. / Many have arrived.
• Collective nouns emphasizing individual members: The team are arguing among themselves. (more common in British English)
• Expressions of quantity with plural nouns: A number of students are present.

Special Plural Cases

Some nouns that look singular are always plural and thus require are:

• Clothing items: The scissors are sharp. / The pants are too long.
• Tools: The tweezers are useful.
• Certain nouns ending in -s: The premises are secure. (meaning buildings)

Subject‑Verb Agreement with Tricky Subjects

Indefinite Pronouns

Indefinite pronouns can be singular, plural, or both depending on context:

This is where a lot of people lose the thread.

When the pronoun refers to an uncountable noun, use is; when it refers to a countable plural noun, use are.

Collective Nouns

Collective nouns name a group but can be treated as singular or plural depending on whether the group acts as a single unit or as individuals:

• Singular (unit): The audience is listening attentively.
• Plural (individuals): The audience are clapping at different times.

American English tends to favor the singular verb, while British English often accepts the plural when emphasizing members And it works..

Subjects Joined by Or or Nor

When subjects are connected by or or nor, the verb agrees with the subject closest to it:

• Neither the teacher nor the students are ready. (plural subject closest)
• Either the students or the teacher is responsible. (singular subject closest)

There Constructions

Sentences that begin with there use is or are based on the noun that follows:

• There is a problem. (singular)
• There are several problems. (plural)

Common Mistakes and How to Avoid Them

1. Matching the verb to a nearby noun instead of the true subject

   • Incorrect: The list of items are on the table.
   • Correct: The list of items is on the table. (The subject is list, not items.)

2. Treating uncountable nouns as plural

   • Incorrect: The informations are correct.
   • Correct: *The information **is

Relative Pronouns

When a relative pronoun introduces a clause, the verb must agree with its antecedent (the noun it refers to), not with the pronoun itself.

Tip: If the antecedent is clear and singular, use is; if it’s plural, choose are. When the antecedent is indefinite (e.That's why g. , someone, anyone), treat it as singular And that's really what it comes down to. And it works..

Indefinite Adjectives

Words like each, every, either, neither, and another always take a singular verb, even though they may refer to multiple items Took long enough..

• Each of the participants is required to sign the waiver.
• Every one of the tickets was sold yesterday.
• Either the manager was or were available for the meeting. (Here the choice depends on whether you view the options as a single scenario (was) or as two separate possibilities (were).)

“One of …” Constructions

The noun one is singular, but the verb that follows often confuses writers And that's really what it comes down to..

• One of the proposals is being considered. (The subject is one, not the proposals.)
• One of the proposals are being considered. (Only acceptable in informal speech where the focus is on the multiple proposals rather than the singular one.)

“The Number” vs. “The Numbers”

• The number (singular) → is
  The number of applicants is rising.

• The numbers (plural) → are
  The numbers on the scoreboard are updated after each basket.

“The Team” in Different Contexts

• Singular (team as a unit) → is
  The team is practicing tonight.

• Plural (team members as individuals) → are
  The team are arguing about the strategy.

American English typically prefers the singular, while British English allows both forms depending on emphasis.

Quick Reference Checklist

• Singular subjects (name, title, most nouns) → is
• Plural subjects (names, tools, clothes, multiple nouns) → are
• Uncountable nouns (information, advice, luggage) → is
• Indefinite pronouns – singular when referring to uncountable or a single entity, plural when referring to multiple countable items.
• Collective nouns – choose is for unit action, are for individual actions.
• Subjects joined by or/nor – verb agrees with the nearest subject.
• There + verb – match the verb to the noun that follows.
• Relative pronouns – verb agrees with the antecedent, not the pronoun.
• Indefinite adjectives (each, every, either, neither, another) → singular verb.
• One of … → singular verb (subject = one).
• The number → singular verb; the numbers → plural verb.

Conclusion

Mastering the choice between is and are hinges on recognizing the true grammatical number of the subject in each sentence. Day to day, by paying attention to singular versus plural nouns, uncountable versus countable concepts, collective behavior, and the nuances of indefinite pronouns and adjectives, you can avoid common agreement errors and write with confidence.
