Is there any verb which means that I lost something but actually you're sure that it isn't lost forever? So I don't know where is it now but if I was looking for it, I would find it. Or, I put it somewhere but now I don't remember where and I can't find it.
I _____ my car keys in the hurry.
I _____ your book but I'll give it back as soon as I find it.
Or should I just simply use "lost"?
(In my mind "lost" is permanent, and I'm looking for a word which means the same but only temporarily.)
