Walk a short way, then take a bus (6)
I believe the answer is:
stride
'walk' is the definition.
(stride can mean to walk around)
'a short way then take a bus' is the wordplay.
'a short way' becomes 'st' (abbreviation for street; 'short' suggests a short form).
'then' means one lot of letters go next to another.
'take a bus' becomes 'ride' (I've seen this in another clue).
'st'+'ride'='STRIDE'
(Other definitions for stride that I've seen before include "Walk along in direst way" , "A lengthy step" , "use your legs!" , "Long step of direst kind" , "jazz piano-playing" .)
