Carpet salesman also on edge (9)
I believe the answer is:
reprimand
'carpet' is the definition.
(I know that carpet can be written as reprimand)
'salesman also on edge' is the wordplay.
'salesman' becomes 'rep' (sales representative).
'also' becomes 'and' (both can mean in addition).
'on' says to put letters next to each other.
'edge' becomes 'rim' (rim is a kind of edge).
'and' put after 'rim' is 'rimand'.
'rep'+'rimand'='REPRIMAND'
(Other definitions for reprimand that I've seen before include "Formal rebuke" , "Tick off - carpet" , "Official scolding" , "Expression of disapproval" , "Formal censure" .)
