In English, the Third Person Singular refers to the form used for a single third-person subject. In English verbs, the verb form usually changes depending on the person and number of the subject. Specifically, the third person singular refers to situations where the subject is “he,” “she,” “it,” or a single noun. In the present tense, the verb usually ends with “-s” when it is in the third person singular.

For example, consider the following sentences:

  1. He plays football. (他踢足球。)
  2. She sings beautifully. (她唱得很美。)
  3. It runs fast. (它跑得快。)

In these examples, “plays,” “sings,” and “runs” are all verbs that end with “-s” to match the third-person singular subject (“he,” “she,” and “it”).

Note that the third person singular applies only to the Simple Present Tense. In other tenses, such as the Simple Past Tense, Present Continuous Tense, Simple Future Tense, etc., the verb form will be different.

When discussing English verb tenses, here are some examples of the third person singular across different tenses:
