Cavalryman engages a paid club entertainer (3,6)
I believe the answer is:
lap dancer
'club entertainer' is the definition.
'lap dancer' can be an answer for 'entertainer' (I've seen this before). I am unsure of the 'club' bit.
'cavalryman engages a paid' is the wordplay.
'cavalryman' becomes 'lancer' (lancer is a kind of cavalryman).
'engages' indicates putting letters inside.
'paid' becomes 'pd' (I've seen this in other clues).
'a'+'pd'='apd'
'lancer' enclosing 'apd' is 'LAP DANCER'.
Can you help me to learn more?
(Other definitions for lap dancer that I've seen before include "performer" , "one barely performs" , "Erotic entertainer" , "she barely moves close" , "stripper" .)
