See tradesmen for talks (8)
I believe the answer is:
chatters
'talks' is the definition.
(chattering is a kind of talking)
'see tradesmen' is the wordplay.
I cannot quite see how this works, but
'see' could be 'c' (the word for the letter, according to Chambers) and 'c' is found in the answer.
The remaining letters 'hatters' is a valid word which might be clued in a way I don't understand.
This may be the basis of clue (or it may be nonsense).
'for' acts as a link.
Can you help me to learn more?
(Other definitions for chatters that I've seen before include "Blabbers" , "Talks idly" .)
