Walk or, for a short way, go by bus (6)
I believe the answer is:
stride
'walk' is the definition.
(stride can mean to walk around)
'way go by bus' is the wordplay.
'way' becomes 'st' (abbreviation for street).
'go by bus' becomes 'ride' (I've seen this in another clue).
'st'+'ride'='STRIDE'
'or for a short' acts as a link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for stride that I've seen before include "Long step of direst kind" , "use your legs!" , "Long decisive step" , "Long walking step" , "Step out energetically" .)
