Trot or walk (4)
I believe the answer is:
gait
This clue is a double definition.
'trot' is the first definition.
(I've seen this in another clue)
'walk' is the second definition.
(gait is a kind of walk)
(Other definitions for gait that I've seen before include "Walk" , "Bearing" , "Manner of walking or running" , "Carriage" , "walkway?" .)
