Standing out (7)
I believe the answer is:
salient
'standing out' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for salient that I've seen before include "part of defences" , "Leaping (heraldry)" , "Outstanding - it's lean (anag)" , "Prominent, most noticeable" , "obvious" .)
