Number, Person, and Inflection in Verb Agreement
Number refers to the grammatical category of whether a verb is singular or plural, which must agree with the number of the subject.
- Singular verbs are used with singular subjects, such as "he," "she," "it," or "the boy."
- Plural verbs are used with plural subjects, such as "they," "we," "you all," or "the girls."
Example:
- The boy sings a beautiful song. (Singular subject, singular verb)
- The girls sing beautifully. (Plural subject, plural verb)
Person refers to the grammatical category of the subject, namely first, second, or third person. A verb must agree with the person of its subject.
- First person verbs are used with subjects representing the speaker, such as "I" or "we."
- Second person verbs are used with subjects representing the person being spoken to, such as "you" or "you all."
- Third person verbs are used with subjects that do not represent the speaker or the person being spoken to, such as "he," "she," "it," or "they."
Example:
- I sing in the choir every Sunday. (First person subject, first person verb)
- You read very well. (Second person subject, second person verb)
- He plays the piano beautifully. (Third person subject, third person verb)
Inflection refers to the changes in the form of the verb to indicate person, number, and tense. Different languages have different ways of marking inflection on verbs.
Example:
| Person | Number | Present Tense Inflection |
|---|---|---|
| First | Singular | -s |
| Second | Singular | Zero |
| Third | Singular | Zero |
| First | Plural | Zero |
| Second | Plural | Zero |
| Third | Plural | -s |
Example:
- I sing.
- You sing.
- He sings.
- We sing.
- You all sing.
- They sing.
Incorrect Example:
- The boy sings beautifully. (Incorrect because the verb is in the singular form, but the subject is plural.)
- I sing a beautiful song. (Incorrect because the verb is in the first person singular form, but the subject is second person singular.)
