Sign of kiss inside collar after this? (4)
I believe the answer is:
next
'after this?' is the definition.
(I've seen this in another clue)
'sign of kiss inside collar' is the wordplay.
'sign of kiss' becomes 'X' (X can represent a kiss).
'inside' is an insertion indicator.
'collar' becomes 'net' (both can mean to apprehend).
'x' put within 'net' is 'NEXT'.
(Other definitions for next that I've seen before include "The second cherry stone on the plate" , "Closest" , "Immediately afterwards" , "Coming nearest in time or sequence" , "Subsequent" .)
