Mosque feature (7)
I believe the answer is:
minaret
'mosque feature' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for minaret that I've seen before include "Mosque's tower" , "Mosque turret" , "Slender mosque tower" , "Slim tower of a mosque" , "Appropriate raiment for mosque tower" .)
