Writer of novel bickers when losing $1000 (6)
I believe the answer is:
scribe
'writer' is the definition.
(scribe is a kind of writer)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for scribe that I've seen before include "Scholar of Jewish law" , "Document writer" , "Copier of (handwritten) documents" , "Mark with a sharp point" , "Letter-writer of old" .)
