Answer:
Present: I, you, they, we come. He, she, it comes.
Past: came (irregular verb)
Past Participle: had come
Step-by-step explanation:
Present simple: I, you, we, they come.
When you use the 3er person singular in the present tense you must add a final "s" or "es" to the verb. In this case the verb "come" has a final "e" so you must add just a final "s".
For example: He, she, it comes.
Past simple: I, you, we, they, he, she, it came (irregular verb).
Regular verbs in the past tense must have a final "d" or "ed" to show that the verb is in the past tense. On the other hand irregular verbs like "come" has a special form in the past tense.
Past Participle: I, we, you, they, she, he, it had come.
