Cheats a chap out of love (4)
I believe the answer is:
does
'cheats' is the definition.
The definition and answer can be both to do with social activities as well as being verbs in their -s form.
Perhaps you can see a link between them that I don't see?
'a chap out of love' is the wordplay.
I cannot really understand how this works, but
'of' could be 'o' and 'o' is found within the answer.
'chap' could be 'des' and 'des' is found within the remaining letters.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for does that I've seen before include "takes one for a ride" , "Female deers" , "Acts" , "Carries out" , "Deer; performs" .)
