Walk in street / take bus? (6)
I believe the answer is:
stride
'walk' is the definition.
(I've seen this before)
'street take bus?' is the wordplay.
'street' becomes 'st'.
'take' is a charade indicator (letters next to each other).
'bus?' becomes 'ride' (bussing is a kind of riding).
'st'+'ride'='STRIDE'
'in' acts as a link.
(Other definitions for stride that I've seen before include "jazz piano-playing" , "march" , "Walk with long steps" , "Long pace" , "use your legs!" .)
