I have purchased a domain named with 'letallgo', because 'LETITGO' was not available. Now I want to know how does it different from 'letitgo'. Is it mean the same as 'letitgo'. I know it and all has lot difference. Is it worthy?
There are actually 3 phrases: “let it go”, “let it all go”, and “let all go”. “Let it go” usually refers to a thing that has already been mentioned, which should be let go. (Or this song from the movie Frozen.) “Let it all go” means that you should let everything go, or that there are multiple things (that have already been mentioned) that should be let go. “Let all go” is sometimes the same as the former (first) “let it all go”, but it more often means that you should unwind and let yourself go. “Let all go” is also slightly less formal in some cases.
