A walk to the gate I hear (4)
I believe the answer is:
gait
'a walk' is the definition.
(I know that gait is a type of walk)
'the gate i hear' is the wordplay.
'i hear' shows a homophone (sound like).
'gate' sounds like 'GAIT'.
'to' is the link.
(Other definitions for gait that I've seen before include "Manner of walking or running" , "Carriage" , "Bearing" , "Method of moving" , "walkway?" .)
