These rules are included in the right form of verbs.

Hence, we have to use “s/es” with verb “go”.

Rule-1: In present simple tense, we use “s/es” at the ending of the verb when subject is 3rd person singular and “doesn’t” in negative sentence as well as “does” for interrogative at the beginning of that sentence.

Note: For 1st, 2nd and 3rd person plural, we use base form of the verb.
