Pub requires no money for a sort of smoothie? (8)
I believe the answer is:
innocent
'a sort of smoothie?' is the definition.
(Innocent Drinks is a smoothie company)
'pub requires no money' is the wordplay.
'pub' becomes 'inn' (an inn is a type of pub).
'requires' is a charade indicator (letters next to each other).
'no' becomes 'O' (resembles 0 - 'no' can mean 'zero').
'money' becomes 'cent' (eg denomination of dollars).
'inn'+'o'+'cent'='INNOCENT'
'for' acts as a link.
(Other definitions for innocent that I've seen before include "Without blame or guilt" , "not intending to cause offence?" , "Free from evil or guilt" , "Giovanni Lotario de' Conti?" , "Free of any blame" .)
