Hey __ __ swindle! (6)
I believe the answer is:
diddle
'swindle' is the definition.
(I know that swindle can be written as diddle)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for diddle that I've seen before include "Slang for cheat or swindle - nearly fiddle" , "Fleece" , "Did, and led out to cheat" , "Con - do - lidded (anag)" , "Slangily cheat or swindle" .)
