A record player with a coin nearby (8)
I believe the answer is:
adjacent
'nearby' is the definition.
(I've seen this before)
'a record player with a coin' is the wordplay.
'record player' becomes 'dj'.
'with' means one lot of letters go next to another.
'coin' becomes 'cent' (cent is a kind of coin).
'a'+'dj'+'a'+'cent'='ADJACENT'
(Other definitions for adjacent that I've seen before include "Nearby" , "Alongside" , "Next (to something)" , "Next-door" , "Neither opposite nor hypotenuse?" .)
