Reprimand from Oscar Peterson (6)
I believe the answer is:
carpet
'reprimand' is the definition.
(carpet can informally mean to reprimand or rebuke)
'from oscar peterson' is the wordplay.
'from' indicates a hidden word.
'CARPET' can be found hidden inside 'oscar peterson'.
(Other definitions for carpet that I've seen before include "Woven fabric for the floor" , "lecture?" , "Reprimand severely" , "Large rug" , "Pet car on the floor" .)
