Lean or bony (7)
I believe the answer is:
angular
I believe this is a double definition.
'lean' is the first definition.
(I've seen this in another clue)
'bony' is the second definition.
(I've seen this before)
(Other definitions for angular that I've seen before include "Pointed" , "Scrawny" , "With prominent bone structure" , "with geometric design" , "Sharp cornered" .)
