Indicated novel gets rude (8)
I believe the answer is:
gestured
'indicated' is the definition.
(indicated through gestures)
'novel gets rude' is the wordplay.
'novel' indicates an anagram.
'gets'+'rude'='getsrude'
'getsrude' with letters rearranged gives 'GESTURED'.
(Other definitions for gestured that I've seen before include "Signalled, motioned" , "Expressed through movement - gets rude (anag)" .)
