Describing movement showing some combination of rage and lust (8)
I believe the answer is:
gestural
'describing movement' is the definition.
'combination of rage and lust' is the wordplay.
'combination of' is an anagram indicator (I've seen this in other clues).
'and' is a charade indicator (letters next to each other) (I've seen this in other clues).
'rage' after 'lust' is 'lustrage'.
'lustrage' is an anagram of 'GESTURAL'.
'showing some' acts as a link.
(Other definitions for gestural that I've seen before include "Conveyed by hand movements" , "of signals" , "With waving arms" , "Pertaining to meaningful movements" .)
