Look a shot (6)
I believe the answer is:
glance
I believe this is a double definition.
'look' is the first definition.
(I know that glance is a type of look)
'a shot' is the second definition.
(I've seen this before)
(Other definitions for glance that I've seen before include "Peek" , "A brief or casual look" , "Look quickly at -- cricket stroke" , "Flash" , "it has a metallic lustre" .)
