Drunk gets pawn in position (4)
I believe the answer is:
spot
'position' is the definition.
(synonyms)
'drunk gets pawn' is the wordplay.
'drunk' becomes 'sot' (synonyms).
'gets' means one lot of letters goes inside another (gets can mean captures or absorbs).
'pawn' becomes 'p'.
'sot' going around 'p' is 'SPOT'.
'in' is the link.
(Other definitions for spot that I've seen before include "See - blemish" , "Notice; skin blemish" , "20 [MARK]" , "Catch sight of mark in pots" , "Mark, dot" .)
