Talk about event in field with sons (7)
I believe the answer is:
discuss
'talk about' is the definition.
(to discuss something is to talk about it)
'event in field with sons' is the wordplay.
I cannot really see how this works, but
'sons' could be 'ss' (s is abbreviation for son) and 'ss' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for discuss that I've seen before include "Talk about (something)" , "Go into" , "Consider" , "Verbally T [TREAT]" , "Debate" .)
