Saunter on street and go round (6)
I believe the answer is:
stroll
'saunter' is the definition.
(I know that saunter can be written as stroll)
'street and go round' is the wordplay.
'street' becomes 'st' (abbreviation).
'and' is a charade indicator (letters next to each other).
'go round' becomes 'roll' (I've seen this in other clues).
'st'+'roll'='STROLL'
'on' acts as a link.
(Other definitions for stroll that I've seen before include "Walk in a leisurely way" , "Walk slowly and idly" , "A quiet, pleasant walk" , "Saunter in no particular direction" , "cinch" .)
