Victor misses front part of target (5)
I believe the answer is:
inner
'part of target' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for inner that I've seen before include "Private, not expressed" , "Central, internal" , "Target area" , "Exclusive to a center" , "Area near to bull's-eye" .)
