Criticize a gripe, sad, out of order (9)
I believe the answer is:
disparage
'criticize' is the definition.
(disparaging is a kind of criticizing)
'a gripe sad out of order' is the wordplay.
'out of order' indicates anagramming the letters.
'a'+'gripe'+'sad'='agripesad'
'agripesad' with letters rearranged gives 'DISPARAGE'.
(Other definitions for disparage that I've seen before include "Belittled" , "Slight" , "Run down" , "Scorn" , "I grasped a change to belittle" .)
