Answer 2

Hi, and welcome to the forum.

You are asking this: Is the affirmative second person singular informal imperative command the same verb form as the third person singular indicative?

Having read that, there is merit in the way you asked it!

Anyway, the answer is yes. To say (You, the person I know) Think! you would say:

¡Piensa! Piensa is the third person singular, indicative tense, of pensar.
