Beat at golf, possibly? (4)
I believe the answer is:
flog
'beat' is the definition.
(I know that flog is a type of beat)
'golf possibly?' is the wordplay.
'possibly?' indicates anagramming the letters (I've seen 'possibly' mean this).
'golf' is an anagram of 'FLOG'.
'at' acts as a link.
(Other definitions for flog that I've seen before include "- - a dead horse" , "Keep hitting" , "Swing a cat, perhaps" , "Hit - sell" , "Whip severely" .)
