Walk, say, to get takings (4)
I believe the answer is:
gate
'takings' is the definition.
(thesaurus)
'walk say' is the wordplay.
'walk' becomes 'gait' (gait is a kind of walk).
'say' indicates a 'sounds like' (homophone) clue.
'gait' sounds like 'GATE'.
'to get' acts as a link.
(Other definitions for gate that I've seen before include "Attendance at a sporting event" , "Five-bar opening?" , "Attendance; entrance" , "Airport boarding point" , "Spectators - entrance" .)
