I'd. Usage and meaning

[diplomacy]

I'd rather you explained to her why we can't go.

I have two questions on the above sentence.

1/ Is I'd I had?

2/ in which situation we should use this sentence?

 

[SoothingDave]

1. No, it means "I would."
2. When you would rather have someone explain to her why you can't go.

Thanks a lot.

What I know is after would the verb is an infinitive verb .however the above sentence doesn't match with that why?

"I'd" means either "I would" or "I had", the latter only when being used to form the pluperfect. (I use it to mean both as a BrE speaker)

And what do you mean the above sentence doesn't "match with" the rule that a modal most times must be followed by an infinitive? "You would rather have" But I think that example is not the best. Here are some more:
I'd (would) go with you, but I have to do my homework.
I'd (had) forgotten to tell her I was cleaning the car.
