Centre of target (5-3)
I believe the answer is:
bulls-eye
'centre of target' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for bulls-eye that I've seen before include "The centre of a shooting target" , "Accurate shot" , "Window - sweet" , "Light - gold - sweet" , "Centre of the target (4'1, 3)" .)
