Final answer:
In English, the subject and verb in a sentence must agree. Singular subjects take singular verbs, while plural subjects take plural verbs, with a few exceptions.
Step-by-step explanation:
In English, the subject of a sentence must agree with the verb. Singular subjects take singular verbs, while plural subjects take plural verbs.
For example:
- Singular: The cat is sleeping.
- Plural: The cats are sleeping.
However, there are some exceptions, such as collective nouns and certain nouns ending in -s. Additionally, compound subjects joined by 'and' usually take plural verbs, but when they represent a single unit, the verb is singular.
