Roamed the street with ready change (7)
I believe the answer is:
strayed
'roamed' is the definition.
('stray' can be a synonym of 'roam')
'street with ready change' is the wordplay.
'street' becomes 'st' (abbreviation).
'with' says to put letters next to each other.
'change' indicates an anagram.
'ready' is an anagram of 'rayed'.
'st'+'rayed'='STRAYED'
'the' acts as a link.
(Other definitions for strayed that I've seen before include "Wandered off course" , "Dry seat (anag) - got lost" , "Went off the track" , "Wandered away" , "Went off course" .)
