Rod will do a swap with you (6)
I believe the answer is:
switch
'rod' is the definition.
(I've seen this before)
'do a swap with you' is the wordplay.
I cannot really see how this works, but
'with' could be 'w' (short for with) and 'w' is located in the answer.
The remaining letters 'sitch' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
'will' is the link.
Can you help me to learn more?
(Other definitions for switch that I've seen before include "Contact maker or breaker" , "Light whip - light control" , "Electrical control - change sides" , "Change over - whip" , "Sudden change; a rod" .)
