Quarrel as yet unfinished? (2-2)
I believe the answer is:
to-do
I believe this clue is a double definition.
'quarrel' is the first definition.
(I've seen this before)
'as yet unfinished?' is the second definition.
(still to complete)
(Other definitions for to-do that I've seen before include "Fuss and bother" , "Flap" , "Bustle" , "Fuss or commotion" , "Kerfuffle" .)
