1. Subject – Verb Agreement Rules
If it sounds wrong, it probably is…

2. A singular subject demands a singular verb;
a plural subject demands a plural verb.
That is the simple principle behind subject-verb agreement.
Tip:
***Singular verbs end in s
Example: She runs very fast.
***Plural verbs don’t
Example: They run very fast.

3. Subjects Joined by “and”…
When the subject of a sentence is composed of two or more nouns or pronouns connected by and, You almost always should use a plural verb. You can replace the subjects with the pronoun they, and you will always get the right answer.
Ex: She and her friends (is, are) at the fair.
Answer: They (are) at the fair.

4. Compound Subjects Preceded by Each, Every, Many a, or No…
When you have two subjects joined by “and” but preceded by “each” or “every”, “many a”, or “no”, you should use a singular verb. You can replace the subject with “he”, “she”, or “it” and it will work.
Ex: Every aunt and uncle (was, were) at the reunion.
He (was) at the reunion.
Ex: Each lion and tiger (is, are) dangerous.
It (is) dangerous.

5. Subjects Joined by “or” or “nor”,
When a compound subject is joined by “or” or “nor”, the verb should agree with the part of the subject that is nearer the verb.
If it is singular, replace with “he”, “she”, or “it.”
If it is plural replace with “they.”
Ex: The boy or his friends (runs, run) every day.
They (run) every day.
Ex: His friends or the boy (runs, run) every day.
He (runs) every day.

6. Sentences Beginning with “There”
In sentences beginning with “there is” or “there are”, the verb agrees with the word/words that follows the verb.
Ex: There are many questions.
Ex: There is a question.

7. Collective Nouns
Collective nouns are words that imply more than one person but that are considered singular and usually take a singular verb, such as: group, team, committee, class, and family. You can replace the subject with “he”, “she”, or “it.”
Ex: The class (want, wants) a recess.
He (wants) a recess.

8. Singular Indefinite Pronouns
The indefinite pronouns that end in “one”, “body”, or “thing” are always singular and, therefore, require singular verbs. You can replace them with “he”, “she” or “it” and it will always work.
Ex: Everyone (has, have) done homework.
He (has) done homework.

9. Plural Indefinite Pronouns
Plural indefinite pronouns such as: some, many, few, several, are plural and can be replaced with “they” to use with the plural verb.
Ex: Several of the girls (swim, swims) on the team.
They (swim) on the team.

10. Distributive Pronouns
The pronouns each, neither and either are singular and require singular verbs even though they seem to be referring, in a sense, to two things. You can replace it with “he”, “she”, or “it” and it will work.
Ex: Neither of the two traffic lights (is, are) working.
It is working.
Ex: Either shirt (is, are) fine with me.
It is fine with me.

11. Phrases between the Subject & Verb
You should ignore any phrases between the subject and verb, remembering to just look at the subject.
Ex: Everyone of the girls (is, are) tired.
She (is) tired.
Ex: Melody, as well as her sisters, (like, likes) running.
She (likes) running.

12. Special Plural Subjects
Some other nouns are always considered plural and should be used with a plural noun. You can replace them with the pronoun “they” and it will always work.
Ex: pincers, pliers, scales, scissors, shears, tongs, tweezers, clothes, glasses, trousers, suspenders, ashes, proceeds, thanks
Ex: The pliers (are, is) in the shed.
They (are) in the shed.

Since the subjects are joined by “and” and represent two different objects, you can replace them with “they”. They like the new car.
Black and blue (is, are) my favorite color combination.
Although the subjects are joined by “and” they represent one combination (singular SC). You should replace with “it” to find the subject. It is my favorite color combination.

22. Answers The girls or the boy (like, likes) science best.
Since subjects are joined by “or” use the one closest to the verb: boy likes science best.
Each of the cars (race, races) down the street.
Since the subject is a singular distributive pronoun, you can use: It races.
Every boy and girl (make, makes) a toy.
The two subjects joined by “and” have “every” in front of them, which makes the subject singular. You can use: he makes a toy.
