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.
Maybe you can see an association between them that I can't see?
'a chap out of love' is the wordplay.
'a chap' becomes 'des' (**).
'out of' means one lot of letters goes inside another.
'love' becomes 'o' (In tennis, 'love' means 'zero').
'des' placed around 'o' is 'DOES'.
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" .)
