After little time, study walk (5)
I believe the answer is:
tread
'walk' is the definition.
(treading is a kind of walking)
'after little time study' is the wordplay.
'after' means one lot of letters go next to another.
'little time' becomes 't' (abbreviation for time).
'study' becomes 'read' ('read' can be a synonym of 'study').
't'+'read' is 'TREAD'.
(Other definitions for tread that I've seen before include "Walk; part of tyre" , "Grooved surface of a tyre" , "Top surface of a stair step" , "Trample" , "Surface of car tyre" .)
