Student or Learner
Please clarify me what's the difference between could and would. I tried to understand it by myself, but unfortunately I didn't get.
I wish I could have gone with you.
I wish I would have remembered to take the dog out.
"I wish I could have gone with you" and
"I wish I would have gone with you"?
(The answer is still the same as bhaisahab gave; the second isn't grammatical if you mean "I wish I had gone with you").
I have to agree that "I wish (whoever) would have..." is actually pretty common in the US. One of those things we say, but wouldn't necessarily write.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
