Liveinjapan  +  502836 Sun, 20 Apr 08 02:03 AM If I had known you would be late, I would've waited for you. I think this is correct. Can I say without changing the meaning, If I had known you were late, I would've waited for you. I think the fact that you were late is what the speaker already know right now, so the past simple could be used in the if-clause. It could be casual spoken English, though.

	New2grammar  +  502837 Sun, 20 Apr 08 02:09 AM This is what I think. "If I had known" put you back in time to the point where you didn't know she would/wouldn't come. I hope this makes sense to you. So, I would choose the first one. New2grammar Joined on Tue, Nov 21 2006 Veteran Member 7,676 Who wants to go sailing around the world with me?

	Yoong Liat  +  502838 Sun, 20 Apr 08 02:14 AM Hi LiJ If I had known you would be late, I would've waited for you. (correct) The other sentence is not correct. The fact is that you had not known he would be late, and so you had not waited for him. Yoong Liat Joined on Mon, Sep 4 2006 Veteran Member 6,757

	Liveinjapan  +  502873 Sun, 20 Apr 08 03:51 AM Thanks, New2 and YL. I agree with you. I wonder if natives say 'you were late' in very casual spoken English. Liveinjapan

	Grammar Geek  +  502877 Sun, 20 Apr 08 04:28 AM I'm just having trouble making sense of this at all. If I'd have known you were going to be so late, I never would have waited for you -- now that makes sense. If I'd know you were going to be only a little late, I would have waited for you. But the way this is written, I didn't wait for you (at all). So your being late would have made me wait? How odd - since back when I thought you were going to be on time, I still didn't wait.
