This is a basic question though, please teach me if there is any meaning difference
between " I'd have ..." and " I would've ...".

Do you use " I' d ve... ", too?

Hi guys,
This is a basic question though, please teach me if there is any meaning difference
between " I'd have ..." and " I would've ...". Not much at all. Perhaps #1 focuses a bit more on the act you are talking about, and #2 focuses a bit more on the fact that the act is conditional / hypothetical. But really, there's very little difference.

Do you use I'd've... , too? Yes, all the time, very common in speech.

Best wishes, Clive

As far as my experience goes, I have only seen the usage of I'd have contraction.
