Yen to buy it? (5,4)
I believe the answer is:
death wish
'it?' is the definition.
I can't tell whether this definition defines the answer.
'yen to buy' is the wordplay.
'yen' becomes 'wish' (I've seen this in another clue).
'to' says to put letters next to each other (I've seen this in other clues).
'buy' becomes 'death' (I can't explain this - if you can you should believe this answer much more).
'wish' after 'death' is 'DEATH WISH'.
Can you help me to learn more?
(Other definitions for death wish that I've seen before include "destructive feeling" , "Unconscious desire to end it all" , "Desire for self-annihilation" , "Desire to pass on" , "Reason for very reckless acts?" .)
