Take long steps in street, and trip (6)
I believe the answer is:
stride
'take long steps' is the definition.
(I've seen this before)
'street and trip' is the wordplay.
'street' becomes 'st'.
'and' says to put letters next to each other.
'trip' becomes 'ride' (I've seen this before).
'st'+'ride'='STRIDE'
'in' acts as a link.
(Other definitions for stride that I've seen before include "Long pace" , "Take a long step" , "A big step forward" , "Move with long steps" , "Walk along in direst way" .)
