Victor misses top of target (5)
I believe the answer is:
inner
'target' is the definition.
(I've seen this before)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for inner that I've seen before include "Exclusive to a center" , "Deep" , "(Of thoughts) intimate - (of circles) privileged" , "Esoteric" , "Annulus nearest bull" .)
