Assume I'm having a drink with drug (7)
I believe the answer is:
imagine
'assume' is the definition.
(I've seen this before)
'i'm having a drink with drug' is the wordplay.
'having' is a charade indicator (letters next to each other).
'drink with' becomes 'gin' (gin is a kind of drink. I am not sure about the 'with' bit.**).
'drug' becomes 'e' (e is another name for ecstasy).
'im'+'a'+'gin'+'e'='IMAGINE'
Can you help me to learn more?
(Other definitions for imagine that I've seen before include "Suppose; think up" , "Suspect" , "that Lennon composed" , "Lennon song - dream" , "Picture to oneself" .)
