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