Question

how can we describe these types affermative negativ intronagitive

Answer 1

A sentence is affirmative if it states something, in a positive sense. Example, "I am certain that this answer is correct". To 'affirm' means to state or assert positively.
Negative is just the opposite. It also makes a statement, but in a negative sense. "I have no doubt that this answer is correct"
Interrogative is when you ask a question. "Are you certain that this answer is correct?"
