Free from obscurity (5-3)
I believe the answer is:
clear-cut
'free from obscurity' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for clear-cut that I've seen before include "Sharply defined" , "Well-defined" , "Cruel act (anag)" , "Very distinct, not open to doubt" , "Unambiguous" .)
