Mention freer translation (5)
I believe the answer is:
refer
'mention' is the definition.
(I know that mention can be written as refer)
'freer translation' is the wordplay.
'translation' is an anagram indicator.
'freer' is an anagram of 'REFER'.
(Other definitions for refer that I've seen before include "Make allusion, or turn to for information" , "Direct elsewhere" , "Be relevant (to)" , "If special treatment needed, GP might do this" , "Fail (an exam candidate)" .)
