Master the golden rule of grammar — the subject and verb must always agree! Learn 15 essential rules with fun examples.
Welcome, grammar champion! Every sentence has two key players — the subject (who or what the sentence is about) and the verb (the action or state). For a sentence to be correct, the subject and verb must agree in number. This means:
Takes a singular verb
Takes a plural verb
See Agreement in Action!
In English, singular verbs often end in -s (he runs, she writes), but plural verbs do not (they run, they write). This is the opposite of nouns, where plural nouns end in -s! Tricky, right?
A singular subject takes a singular verb. A plural subject takes a plural verb. If you remember just this one rule, you are already halfway there!
Here are the 15 most important rules you need to know. Each rule comes with clear examples to help you remember!
When the subject is one person, thing, or idea, the verb must also be singular (usually ends in -s / -es).
When the subject is more than one, the verb takes the base form (no -s).
When two or more subjects are connected by and, they form a compound subject and take a plural verb.
When subjects are connected by or, nor, either...or, or neither...nor, the verb agrees with the subject closest to it.
When either or neither is used as a pronoun (without or/nor), it is always singular.
Distributive words like each, every, everyone, everybody, everything, anyone, nobody, someone are always singular.
Nouns like team, family, class, committee, army, crowd refer to a group as one unit, so they take a singular verb.
Nouns that cannot be counted (like water, milk, information, furniture, advice) are always singular.
These words end in -s but refer to a single subject, discipline, or concept.
These words do not end in -s but always refer to more than one, so they take a plural verb.
A number of means "many" → plural verb. The number of means "the total count" → singular verb.
In the pattern "One of the + plural noun", the subject is one (singular), so the verb is singular.
When a distance, sum of money, or period of time is treated as a single unit, use a singular verb.
In sentences starting with there, the real subject comes after the verb. The verb must agree with that real subject.
Even if a title looks plural, it refers to one thing (one book, one movie, one country), so it takes a singular verb.
Singular subject = verb with -s (He plays)
Plural subject = verb without -s (They play)
Think of it as: "One S is enough!" — either the subject or the verb ends in -s, but rarely both!
These are the sneaky situations where students often make mistakes. Pay close attention!
Sometimes extra words (like a prepositional phrase) appear between the subject and the verb. Ignore them! The verb must still agree with the real subject.
Cross out the words between the subject and verb mentally. Then check: does the subject match the verb?
"The box of chocolates is..." — Yes! "Box" + "is" = both singular. Correct!
In some sentences, the verb comes before the subject. You must find the real subject to decide the correct verb.
When who, which, or that is the subject of a clause, the verb agrees with the antecedent (the word the pronoun refers to).
Phrases like along with, together with, as well as, in addition to, besides do not change the number of the subject. The verb agrees with the first subject only.
