Vehicle on pavement edge clipped street performer (6)
I believe the answer is:
busker
'street performer' is the definition.
(I've seen this before)
'vehicle on pavement edge clipped' is the wordplay.
'vehicle' becomes 'bus' (I've seen this before).
'on' means one lot of letters go next to another.
'pavement edge' becomes 'kerb' (I've seen this before).
'clipped' means to remove the last letter.
'kerb' with its final letter removed is 'ker'.
'bus'+'ker'='BUSKER'
(Other definitions for busker that I've seen before include "player in street" , "Street performer" , "Street entertainer" , "Street musician" , "Public entertainer" .)
