Hi. Is it possible to say "Ask from you" in a sentence?
I was just wondering since people would like to receive things from people. Is it possible to ask something from someone? Thanks.
Yes, but I think 'ask of you' is more usual.

eg The only thing I ask from you is your eternal love.
eg What I want to ask from you is the loan of your car.

But note that this is not a very common phrase.
