What follows ninth cut in canvas cover (4)
I believe the answer is:
tent
'canvas cover' is the definition.
(canvas shelter)
'what follows ninth cut' is the wordplay.
'what follows ninth' becomes 'tenth' (10 comes after 9).
'cut' means to remove the last letter.
'tenth' with its final letter removed is 'TENT'.
'in' acts as a link.
(Other definitions for tent that I've seen before include "abode meant to be temporary" , "Bivvy" , "Canvas shelter; wine" , "Cloth shelter" , "some guys held on to?" .)
