Prominent or conspicuous (7)
I believe the answer is:
salient
This clue is a double definition.
'prominent' is the first definition.
(I know that prominent can be written as salient)
'conspicuous' is the second definition.
(similar in meaning)
(Other definitions for salient that I've seen before include "defence work" , "Leaping (heraldry)" , "obvious" , "Entails being most noticeable" , "Conspicuous; pointing outwards" .)
