Chaucer, e.g., rejected revised offer - wisely, ultimately? (8)
I believe the answer is:
geoffrey
'chaucer' is the definition.
('Geoffrey Chaucer' can be a synonym of 'chaucer')
'e g rejected revised offer wisely ultimately?' is the wordplay.
'rejected' says the letters should be written in reverse.
'revised' indicates an anagram.
'ultimately?' says to take the final letters (I've seen 'ultimately' mean this).
The final letter of 'wisely' is 'y'.
'e'+'g'='eg'
'eg' reversed gives 'ge'.
'offer' anagrammed gives 'offre'.
'ge'+'offre'+'y'='GEOFFREY'
(Other definitions for geoffrey that I've seen before include "Chap" , "man" , "and 23: English poet" , "- Chaucer, Eng. poet and customs official" , "-- Chaucer, writer" .)
