Morphology

unacceptable = acceptable (transparent) = un + accept + able

The prefix 'un-' clearly negates the meaning of 'acceptable', forming a transparent adjective.

Etymology

Unacceptable breaks into two parts: un- meaning 'not' and accept meaning 'to take or agree to'. So unacceptable describes something you cannot accept or that is not good enough.
