Subject Verb Agreement Rules with Examples
Basic Subject Verb Agreement Rules
Subject verb agreement rules with examples dictate that the subject and verb in a sentence must match in number. A singular subject takes a singular verb, and a plural subject takes a plural verb. This ensures grammatical clarity and prevents confusion regarding who or what is performing an action.
Core Agreement Rules and Examples
| Subject Type | Rule | Correct Example |
|---|---|---|
| Singular | Use a singular verb (usually ends in -s) | The student writes every day. |
| Plural | Use a plural verb (no -s ending) | The students write every day. |
| Compound (and) | Subjects joined by 'and' take a plural verb | Yoga and hiking are healthy. |
| Compound (or/nor) | Verb matches the subject closest to it | Neither the coach nor the players are ready. |
| Collective Nouns | Usually take a singular verb | The jury has reached a verdict. |
| Indefinite Pronouns | Words like 'everyone' take singular verbs | Everyone enjoys a good meal. |
Handling Intervening Phrases
One of the most common errors occurs when words come between the subject and the verb. Phrases starting with as well as, along with, or including do not change the number of the subject. You must ignore these phrases to determine the correct verb form.
- Incorrect: The professor, along with her students, were late.
- Correct: The professor, along with her students, was late.
In this example, 'professor' is the only subject, so the verb remains singular.
Indefinite Pronouns and Quantifiers
Most indefinite pronouns are singular, including anybody, everyone, nothing, and each. However, some pronouns can be singular or plural depending on the noun they refer to, such as all, any, more, most, and some.
- Each of the books is unique.
- Most of the water is gone. (Uncountable noun = singular)
- Most of the books are gone. (Countable noun = plural)
Correct vs. Incorrect Structure
**Singular Subject Focus** - Incorrect: The cat chase the mouse. - Correct: The **cat chases** the mouse. **Plural Subject Focus** - Incorrect: The cats chases the mouse. - Correct: The **cats chase** the mouse. **Either/Or Focus** - Incorrect: Either the apples or the orange are on the table. - Correct: Either the apples or the **orange is** on the table.
The 'S' Swap Tip
A simple way to remember subject verb agreement for most present tense verbs is the 'S' swap: if the subject does not have an 's' (singular), the verb usually needs one. If the subject has an 's' (plural), the verb usually does not.
