Hi
I came across to read a sentence containing a phrase 'sign off.' My question is - generally what does the meaning of sign off? I look up the dictionary at hand, but couldn't find a good explain. Also in the Cambridge online -
http://dictionary.cambridge.org/define.asp?key=95881&dict=CALD, this seems not explain the sentence what I have seen (Maybe that is because my poor comprehension to English.)
The sentence appears in a letter. A asks B to verify if something works (It appears like a procedure for QA). If that works then they can move it to the next step. However, B replies that it is pointless for him to verify because it still requires C to prove it works. The sentence looks like 'It is pointless for me to verify whether it works or not because it still requires C to sign off.' Does the phrase `sign off' mean `prove'? (Sorry I can not remember exactly the whole sentence right now as I do not have that letter at hand.)
Thanks in advice.
