Anger after Greek character shown to be sexy (6)
I believe the answer is:
nubile
'to be sexy' is the definition.
(I've seen this in another clue)
'anger after greek character' is the wordplay.
'anger' becomes 'bile' (I've seen this in another clue).
'after' is a charade indicator (letters next to each other).
'greek character' becomes 'nu' (letter from the Greek alphabet).
'bile' after 'nu' is 'NUBILE'.
'shown' acts as a link.
(Other definitions for nubile that I've seen before include "Old enough for marriage" , "fit for match" , "Sexually mature" , "Sexually attractive" , "Of young woman, marriageable or attractive" .)
