Hello. I'll be very grateful for your help.
1)Is it possible to say "I'll answer your question if you are insisting" or is it "if you insist"?
2)Is the sentence correct "By the time you come, the letter will be ready" or is it "when you come"?
3)Which tense is correct or better (Perfect or Simple) in the context "The letter has been written / is written. You can post it"?
Thank you for all your help.
1. "if you insist" is the phrasing used.
2. Your first sentence is very good. The second phrasing is OK, but the first is better.
3. I'd use "has been written."
