Stride for the entrance, by the sound of it (4)
I believe the answer is:
gait
'stride' is the definition.
(I've seen this in another clue)
'entrance by the sound of it' is the wordplay.
'entrance' becomes 'gate' (type of entrance).
'by the sound of it' shows a homophone (sound like).
'gate' is a homophone of 'GAIT'.
'for the' is the link.
(Other definitions for gait that I've seen before include "Way of walking sounds like way of entry" , "Manner of walking or running" , "Style of walking" , "Bearing" , "Deportment" .)
