Marshal bans turncoat for malice or deceit, say (8,4)
I believe the answer is:
abstract noun
'malice or deceit say' is the definition.
I can't judge whether this definition defines the answer.
'marshal bans turncoat' is the wordplay.
'marshal' is an anagram indicator (I've seen 'marshals' mean this (marshal can mean to gather)).
'bans'+'turncoat'='bansturncoat'
'bansturncoat' anagrammed gives 'ABSTRACT NOUN'.
'for' is the link.
Can you help me to learn more?
(Other definitions for abstract noun that I've seen before include "carelessness perhaps" , "Substantive referring to non-physical thing" .)
