What is so special about the third person singular present tense?

Answer 1

The third person singular form of a verb takes -s or -es.

Some examples:

Run-- I/we/you/they run; he/she/it runs

Pant-- I/we/you/they pant; he/she/it pants

Pass-- I/we/you/they pass; he/she/it passes

Answer 2

The third person singular present tense is significant because it often requires a verb to be conjugated differently than other forms. In English, it usually involves adding an "-s" or "-es" at the end of the verb (e.g., "he runs" or "she teaches"). This form helps to indicate when the subject of the sentence is a singular noun or pronoun.
