Subject-verb agreement means the verb must match its subject in number. A singular subject takes a singular verb; a plural subject takes a plural verb. Example: "The dog barks" (singular) vs "The dogs bark" (plural).
What Is Subject-Verb Agreement?
Subject-verb agreement is a fundamental rule of English grammar: the form of the verb must correspond to the number (singular or plural) of the subject. In the present simple tense, this means adding -s or -es to the verb when the subject is third-person singular (he, she, it, or any singular noun): "She works" but "They work."
At basic levels (A1–A2), agreement seems straightforward. But at B1 level and beyond, several complications arise that trip up even advanced learners. Collective nouns (is the team singular or plural?), indefinite pronouns (does "everyone" need "is" or "are"?), and the "there is/are" structure all require careful attention.
One of the most frequent errors is attraction — letting the verb "agree" with a nearby noun instead of the true subject. In "The quality of the products is excellent," the subject is quality (singular), not products. The intervening prepositional phrase of the products does not change this.
Core Agreement Rules
| Rule | Correct | Incorrect |
|---|---|---|
| Singular subject → singular verb | The dog barks. She reads every day. | The dog bark. |
| Plural subject → plural verb | The dogs bark. They read books. | The dogs barks. |
| Collective noun (unit) | The team is ready. The committee has decided. | The team are ready. (AmE) |
| Indefinite pronoun | Everyone is invited. Nobody knows. | Everyone are invited. |
| There is/are | There is a problem. There are three issues. | There is three issues. |
| Intervening phrase | The price of the tickets is high. | The price of the tickets are high. |
Indefinite Pronouns — Always Singular
The following indefinite pronouns always take a singular verb, even though they refer to multiple people or things: everyone, everybody, everything, someone, somebody, something, anyone, anybody, anything, no one, nobody, nothing, each, either, neither.
| Pronoun | Correct example |
|---|---|
| everyone | Everyone is welcome. |
| nobody | Nobody knows the answer. |
| each | Each student has a different opinion. |
| either | Either answer is acceptable. |
| someone | Someone has left the door open. |
