South American king provided crystal meth for prostitute (9)
I believe the answer is:
sacrifice
'meth for prostitute' is the definition.
I can't judge whether this definition defines the answer.
'south american king provided crystal' is the wordplay.
'south american' becomes 'SA'.
'king' becomes 'CR' (short for Carolus Rex, King Charles in Latin).
'provided' becomes 'if' (eg 'provided it's sunny' means 'if it's sunny').
'crystal' becomes 'ice' (ice is a kind of crystal).
'sa'+'cr'+'if'+'ice'='SACRIFICE'
Can you help me to learn more?
(Other definitions for sacrifice that I've seen before include "Destroy" , "Offering to a god" , "Killed offering to a deity" , "Give up" , "Renounce" .)
