What figure of speech is now?

Answer 1

Had by itself is not a figure of speech. But there are figures of speech that use had.

You've been had.

3. If you have been had, someone has tricked you, for example by selling you something at too high a price.

You've had it now, wait till Dad gets home.

4. If you say that someone has had it, you mean they are in very serious trouble or have no hope of succeeding.

I've had it, I'm going home.

5. If you say that you have had it, you mean that you are very tired of something or very annoyed about it, and do not want to continue doing it or it to continue happening. (INFORMAL)
