"I appreciate (it)..."

You could say, I appreciate your trying,

or I appreciate your attempt, or I appreciate you trying for me..

Yes I know that, thanks. But what about the very sentences I wrote?

Hi Ifc

My preference is usually to eliminate unnecessary words from my writing. The it in your sentences can be t

Yes I agree, in those sentences the "it" was unnecessary, there are of course sentences where "it " is necessary also. Such as, I love it, or It was nice to see you. Where is it? but your sentence, "I appreciate it that you try", while understandable is awkward, try making your sentences as simple and straghtforward as possible, such as, "Thank you for trying".

Chao!

Well, specifically about your sentences, to me, none of them sounded completely natural, thats why we were suggesting other possible sentences..

I appreciate that you try.

I appreciate it that you try.

I love that you try.

I love it that you try.

estas son tus phrases, todos terminan en "that you try" que es la parte que es suena tor

Longman Dictionary of Contemporary English mentions "appreciate that", but not "appreciate it that". However, it mentions "appreciate it if".

We appreciate that caring for children is an important job.
I'd appreciate it if you let me get on with my job.
(From Longman Dictionary)

Correct, "appreciate it" would usually be in the conditional form, such as " I would appreciate it if you would help"

Thanks you all again. I appreciate your help! ^^

I add to what my friends said that it is not proper to use (it )because (it)is a pronoun and (that )is also a pronoun so you can't use two pronouns to point to one thing
