Some discredit heretic over indecisive behaviour (6)
I believe the answer is:
dither
'indecisive behaviour' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
'some discredit heretic over' is the wordplay.
'some' says the answer is hidden in the clue (some parts of the word are used).
'DITHER' is hidden within 'discredit heretic over'.
Can you help me to learn more?
(Other definitions for dither that I've seen before include "Hit red in order to vacillate" , "Keep hesitating" , "Hesitates, be indecisive" , "Be in two minds" , "Agitate indecisively" .)
