Subjects and verbs are definitely the most important participants in a sentence. Remember, the subject is the actor or acting concept in a sentence, and the verb does all the work and tells us what the subject is doing. They are always together. Therefore, it is very important that these two agree.
No matter what happens in their private life, they have to follow the rule that:
A singular subject takes a singular verb.
and
A plural subject takes a plural verb.
How do you recognise whether a subject or a verb is singular (one) or plural (more than one)?
One of the clues, apart from common sense, is in the "s".
If a verb or the auxiliary verbs ends with "s", it is singular.
Auxiliary verbs are words such as: has, is, was.
If a subject ends with "s", it is generally plural.
If that confuses you, the singular verb follows the pronouns: he, she, it.
Here is an example that shows the singular subject and its corresponding verbform:
Singular subject and verb:
| Present tense | Present Perfect | Past tense form of "to be" |
|---|---|---|
| She loves He loves It loves |
She has loved He has loved It has loved |
She was pretty He was pretty It was pretty |
The plural verb follows the pronouns: they, we, you
Plural subject and verb
| Present tense | Present Perfect | Past tense form of "to be" |
|---|---|---|
| They love We love |
They have loved We have loved |
They were pretty We were pretty |
Most of the time, subject-verb agreement is fairly easy. However, there are a few situations when this can be confusing.
Here are some rules:
1. When the subject consists of two or more nouns or pronouns and is connected by "and", you need to use a plural verb.
Examples:
2. When the subject consists of two singular nouns and is connected by either, or, neither, nor, use a singular verb.
Examples:
3. When a compound subject is mixed with one singular and one plural noun and connected with neither, nor, either or, the verb agrees with the subject nearer to it.
Examples:
4. Don't be confused by plural or singular words in a phrase that comes between the subject and the verb.
Examples:
5. Some pronouns point back to another pronoun or noun used earlier. The word to which the pronoun refers is called the antecedent. The personal pronoun must agree with its antecedent in person, gender and number.
Examples:
6. The pronouns each, everyone, everybody, anyone, anybody, someone, and somebody are singular. Don't get confused by what follows after them.
