Answer:
A verb used to form a question is called an interrogative verb.
A verb that refers to a hypothetical situation is called a conditional verb.
Step-by-step explanation:
An interrogative sentence, usually punctuated with a question mark at the end, is a sentence expressing a question. In English, besides the change in intonation - spoken language -, there are also some other changes such as the use of auxiliary verbs or the shift in the position of certain words. Let's study the examples below:
- She enjoys listening to music. (affirmative form)
- Does she enjoy listening to music? (interrogative form)
In the interrogative form, the main verb "enjoy" is not conjugated. Instead, the conjugation comes with the auxiliary verb "do" which, in the third person, becomes "does".
A conditional sentence expresses hypothetical ideas, some being probable, some being completely impossible:
- If it doesn't rain this afternoon, I will go rollerskating.
- If it hadn't rained last night, I could have gone walking with you.
