Subject‑Verb Agreement Rules: Top 10 Things You Must Know

Subject‑verb agreement is one of the most important grammar rules in English. It ensures that the verb matches the subject in number and person, making sentences clear and correct. Here are the top 10 subject‑verb agreement rules every student, teacher, and writer should know.

1. Singular Subjects Take Singular Verbs

If the subject is singular, the verb must also be singular. Example: The cat jumps.

2. Plural Subjects Take Plural Verbs

If the subject is plural, the verb must be plural. Example: The cats jump.

3. Words Between Subject and Verb Don’t Change Agreement

Ignore modifiers or phrases between subject and verb. Example: The little girl, who is wearing gloves, is well‑dressed.

4. Compound Subjects Joined by “And”

• If two subjects are joined by and, use a plural verb. Example: The man and the woman were late.
• Exception: If the two subjects refer to one thing, use singular. Example: Peanut butter and jelly is my favorite sandwich.

5. Indefinite Pronouns

• Singular: Everyone is waiting.
• Plural: Many are excited.

6. Collective Nouns

Treat collective nouns as singular when the group acts as one. Example: The team wins easily. Treat them as plural when individuals act separately. Example: The team are arguing among themselves.

7. Subjects with “Each,” “Every,” or “No”

These words make the subject singular. Example: Each student has a book.

8. Units of Measurement or Time

Use singular verbs for measurements or time. Example: Five minutes is enough.

9. Long or Complicated Subjects

Focus on the head noun, not the nearest word. Incorrect: The arrival of new fall fashions have excited shoppers. Correct: The arrival of new fall fashions has excited shoppers.

10. Special Cases with “He, She, It”

When the subject is he, she, it, or a singular noun, the verb usually ends with ‑s. Example: She likes ice cream.
