Subject-verb agreement

What agreement means#

A verb agrees with its subject when both express the same grammatical number. A singular subject needs a singular verb form, while a plural subject needs a plural verb form.

In the simple present, the pattern can look surprising because the singular third-person form often ends in -s:

• The learner reads carefully.
• The learners read carefully.
• I read carefully.
• You read carefully.

The ending belongs to the verb form; it does not mean the action is plural.

Use a subject-first method#

1. Find the main verb

Identify the word that expresses the action or state. In “The list of topics is useful,” the main verb is is.

2. Ask who or what performs the action

The answer is the subject. The subject in the example is list, not topics.

3. Decide whether the subject is singular or plural

List is singular, so is is correct: “The list of topics is useful.”

Words between subject and verb#

A phrase beginning with words such as of, with, or along with can distract you from the real subject.

• The box of old notebooks belongs in the cupboard.
• The students in the front row ask thoughtful questions.
• The teacher, along with two assistants, prepares the room.

Remove the interrupting phrase temporarily if the sentence feels difficult. “The box belongs” makes the agreement clear.

Indefinite subjects#

Words such as each, everybody, someone, and neither are normally treated as singular in standard formal English.

• Each of the answers has an explanation.
• Everybody needs a clear starting point.
• Neither option works in this sentence.

Common mistakes#

Matching the nearest noun

In “The colour of the walls is calming,” the nearest noun is walls, but the subject is the singular noun colour.

Adding -s to every plural idea

In the simple present, a plural subject normally takes the base form: “The lessons begin at nine,” not “The lessons begins at nine.”

Forgetting irregular forms

The verb be has special forms: I am, you are, he or she is, we are, and they are. The verb have becomes has with a singular third-person subject.

A quick check#

Read the subject and verb without the surrounding details. If “learner reads” or “learners read” sounds complete and matches the intended meaning, the full sentence will usually follow the same agreement pattern.
