Fan with two drinks? (9)
I believe the answer is:
supporter
'fan' is the definition.
(thesaurus)
'with two drinks?' is the wordplay.
'two drinks?' can mean two replacements for 'drink'.
'with' means one lot of letters go next to another.
'drink' becomes 'sup'.
'drink' becomes 'porter' (porter is a kind of drink**).
'sup'+'porter' is 'SUPPORTER'.
(Other definitions for supporter that I've seen before include "angel" , "Stay" , "Fan; heraldic figure" , "Adherent, defender" , "Advocate" .)
