What Is Subject-Verb Agreement?

Subject-verb agreement refers to the grammatical rule that the verb in a sentence must agree in number (singular or plural) with its subject. Simply put:

• If the subject is singular (one person, place, thing, or idea), the verb must be singular.

• If the subject is plural (more than one), the verb must be plural.

Why Is Subject-Verb Agreement Important?

Correct subject-verb agreement is critical because it:

• Ensures clarity: It helps readers or listeners understand who or what is performing the action and when.

• Maintains professionalism: Proper grammar reflects well on the writer or speaker, especially in formal writing.

• Prevents confusion: Incorrect agreement can create ambiguity about the meaning of the sentence.

Common Rules and Exceptions

1. Subjects joined by “and” are plural

  (Here, two subjects joined by "and" require a plural verb.)

2. Subjects joined by “or” or “nor” take a verb that agrees with the closest subject

• Either the teacher or the students are responsible.

• Neither the students nor the teacher is available.
  (The verb agrees with the subject nearest to it.)

3. Collective nouns

• Collective nouns such as team, family, committee may take either singular or plural verbs depending on whether the group acts as one unit or as individuals.

• The team is winning. (acting as one unit)

• The team are arguing among themselves. (acting individually)

4. Indefinite pronouns

• Some indefinite pronouns are always singular: everyone, somebody, each

  • Everyone is invited.

• Some are always plural: few, many, several

  • Many are attending.

• Some can be singular or plural depending on context: all, some

  • All of the cake is gone. (singular)

  • All of the cookies are gone. (plural)

5. Titles, names, and words considered singular

• Titles of books, movies, organizations, etc., even if plural in form, take singular verbs.

Common Mistakes in Subject-Verb Agreement

1. Mistaking plural verbs for singular subjects and vice versa

• Incorrect: The list of items are on the desk.

• Correct: The list of items is on the desk.

2. Confusing the verb with words that come between the subject and verb

• Incorrect: The bouquet of flowers smell lovely.

• Correct: The bouquet of flowers smells lovely.
  (“of flowers” is a prepositional phrase, not the subject.)

3. Errors with compound subjects joined by “or” or “nor”

• Incorrect: Either the manager or the employees is responsible.
