There's much talk from me about fight involving milliner (10)
I believe the answer is:
chatterbox
'there's much talk from me' is the definition.
(talkative person)
'about fight involving milliner' is the wordplay.
'about' becomes 'c' (abbreviation for 'circa').
'fight' becomes 'box' (boxing is a kind of fighting).
'involving' indicates putting letters inside.
'milliner' becomes 'hatter' (synonyms).
'c'+'box'='cbox'
'cbox' placed around 'hatter' is 'CHATTERBOX'.
(Other definitions for chatterbox that I've seen before include "who goes on and on?" , "One using plenty of gas" , "Windbag" , "Bletherer" , "One rabbiting on" .)
