Brutally do Mrs in with skilful hack (9)
I believe the answer is:
wordsmith
This clue might be a double definition.
'brutally do' is the first definition.
Although both the answer and definition are singular nouns, I can't understand how they can define each other.
'mrs in with skilful hack' is the second definition.
The definition and answer can be both people as well as being singular nouns.
Maybe there's a link between them I don't understand?
Can you help me to learn more?
(Other definitions for wordsmith that I've seen before include "he'd be good at coining?" , "Skilled writer or orator" , "Author" , "fluent writer" , "Person skilled at writing" .)
