Carpet salesman on tour (7)
I believe the answer is:
reprove
'carpet' is the definition.
(I've seen this before)
'salesman on tour' is the wordplay.
'salesman' becomes 'rep' (I've seen this before).
'on' means one lot of letters go next to another.
'tour' becomes 'rove' (both can mean to travel around).
'rep'+'rove'='REPROVE'
(Other definitions for reprove that I've seen before include "carpet" , "tick off" , "Chide" , "Rebuke, censure" , "Criticise" .)
