Drama difficult to understand? Don't give in too easily! (4,4,2,3)
I believe the answer is:
play hard to get
'don't give in too easily' is the definition.
'drama difficult to understand?' is the wordplay.
'drama' becomes 'play' (synonyms).
'difficult' becomes 'hard' (associated in meaning).
'to understand?' becomes 'toget' (I can't justify this - if you can you should believe this answer much more).
'play'+'hard'+'toget'='PLAY HARD TO GET'
Can you help me to learn more?
(Other definitions for play hard to get that I've seen before include "Feign unwillingness as negotiating ploy" , "Pretend to be indifferent" , "Prolong suit" , "impenetrable stage production" , "Seem unapproachable or uninterested" .)
