What Is Subject-Verb Agreement?
First things first — let’s define what subject-verb agreement really means:
Definition List:
- Subject: The person, place, thing, or idea that is doing or being something in a sentence.
- Verb: The action word or the linking word that connects the subject to more information.
Subject-verb agreement is the rule that the subject and the verb in a sentence must match in number (singular or plural). For example:
- She runs every morning. (singular subject + singular verb)
- They run every morning. (plural subject + plural verb)
Sounds simple, right? But when you add in tricky subjects, collective nouns, and multiple subjects, things can get complicated fast.
Core Rules of Subject-Verb Agreement
Let’s walk through the fundamental rules, expanding on what your competitor covered and filling in the gaps.
Basic Rules
| Rule | Explanation | Examples |
|---|---|---|
| Singular subjects | Use singular verbs. | The dog barks. |
| Plural subjects | Use plural verbs. | The dogs bark. |
| Subjects joined by "and" | Usually take a plural verb. | Tom and Jerry are friends. |
| Subjects joined by "or" / "nor" | Verb agrees with the subject closest to the verb. | Neither the teacher nor the students are ready. |
| Indefinite pronouns (some, any, none, all) | Most take singular verbs, but some plural. | Everyone is here. / Some of the cake is gone. |
| Collective nouns | Usually singular, but context matters. | The team wins every match. / The team are arguing among themselves. |
When to Watch Out

Special Cases & Nuances

Neither the manager nor the employees are available. - Phrases between the subject and verb can mislead; be cautious:
The book on the table is missing. - Collective nouns can be singular or plural depending on whether you’re emphasizing the group as a whole or individuals:
The committee has approved the plan (singular).
The committee are arguing among themselves (plural).
