Erotic drink I had (5)
I believe the answer is:
cupid
'erotic drink i had' is the definition.
I can't tell whether this defines the answer.
'drink i had' is the wordplay.
'drink' becomes 'cup' (a cup of drink).
'i had' becomes 'i'd' (I'd).
'cup'+'id'='CUPID'
Can you help me to learn more?
(Other definitions for cupid that I've seen before include "Blind god" , "Roman god of love, child archer" , "godlike figure" , "boy with little bow" , "Cherubic symbol for love" .)
