Indicated it is sharp (7)
I believe the answer is:
pointed
I believe this clue is a double definition.
'indicated' is the first definition.
('point' can be a synonym of 'indicate')
'sharp' is the second definition.
('pointed' is associated in meaning with 'sharp')
'it is' acts as a link.
(Other definitions for pointed that I've seen before include "Sharp-ended" , "Of remark, direct and cutting" , "With a tapered tip" , "Barbs" , "Rudely indicated" .)
