Subject-Verb Agreement Rules
-
Rule #1
Subjects and verbs must agree in number.
- Example: The dog growls when he is angry.
- Example: The dogs growl when they are angry.
-
Rule #2
Subordinate clauses that come between the subject and verb don't affect their agreement.
- Example: The dog, who is chewing on my jeans, is usually very good.
- Example: The girls, who are smiling at me, are very sweet.
-
Rule #3
Prepositional phrases between the subject and the verb usually do not affect the agreement.
- Example: The colors of the rainbow are beautiful.
- Example: The boxes under the table are large.
-
Rule #4
When sentences start with "there" or "here," the subject will always be placed after the verb. Some care needs to be taken to identify each part correctly.
- Example: There is a problem with the balance sheet.
- Example: Here are the papers you requested.
-
Rule #5
Subjects don't always come before verbs in questions. Accurately identify the subject before deciding on the proper verb form.
- Example: Where are the pieces of this puzzle?
- Example: Is the principal attending the meeting?
-
Rule #6
If two subjects are joined by "and," they typically require a plural verb.
- Example: The cow and the pig are jumping over the moon.
- Example: Martha and Emily are enemies.
-
Rule #7
The verb is singular if the two subjects separated by "and" refer to the same person or thing as a whole.
- Example: My friend and boss is very dedicated at work.
- Example: Red beans and rice is my mother's favorite dish.
-
Rule #8
If one of the words "each," "every," or "no" comes before the subject, the verb is singular.
- Example: No smoking or drinking is allowed.
- Example: Each bread contains milk and raisins.
-
Rule #9
If the subjects are both singular and are connected by "or," "nor," "either/or," "neither/nor," or "not only/but also," the verb is singular.
- Example: Either Jessica or Christian is to be blamed for the accident.
- Example: Not only Billy but also Mark is going to the party tonight.
-
Rule #10
The only time the object of the preposition determines plural or singular verb forms is when noun and pronoun subjects like "some," "half," "none," "more," or "all" are followed by a prepositional phrase.
- Example: All of the chicken is gone.
- Example: All of the chickens are gone.
- Example: Some of the pizza was eaten.
- Example: Some of the pizzas were eaten.
