Is mute language the same in every language?

IMPROVED: Firstly, please do not refer to Sign Language as mute language.

Secondly, no it is not the same. Just as english nad other languages have varying meanings, dialects, etc., SL has varying meanings, dialects, etc. a Word in english might have the same sound a another Word in a different language, yet mean something enitrely different. So it is in SL, as well.

I dont really think so.
