Peer's hard work, in other words (9)
I believe the answer is:
rephrased
'in other words' is the definition.
(I've seen this before)
'peer's hard work' is the wordplay.
'work' indicates anagramming the letters.
'peers'+'hard'='peershard'
'peershard' with letters rearranged gives 'REPHRASED'.
(Other definitions for rephrased that I've seen before include "freshly set down" , "in other words" .)
