One with much to say about milliner maybe at fight (10)
I believe the answer is:
chatterbox
'one' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'much to say about milliner maybe at fight' is the wordplay.
I cannot quite understand how this works, but
'about' could be 'c' (abbreviation for circa) and 'c' is found in the answer.
'milliner' could be 'hatter' (synonyms) and 'hatter' is present in the answer.
'fight' could be 'box' (boxing is a kind of fighting) and 'box' is located in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
'with' acts as a link.
Can you help me to learn more?
(Other definitions for chatterbox that I've seen before include "talk show star, potentially?" , "One rabbiting on" , "who rabbits on?" , "who goes on and on?" , "Talkative person" .)
