Cold refreshment offered by Greek woman (7)
I believe the answer is:
granita
'cold refreshment' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.
'by greek woman' is the wordplay.
'by' is a charade indicator (letters next to each other).
'greek' becomes 'gr' (abbreviation for Greek).
'woman' becomes 'anita' (woman's name).
'gr' put next to 'anita' is 'GRANITA'.
'offered' acts as a link.
Can you help me to learn more?
(Other definitions for granita that I've seen before include "Kind of water ice - a rag tin (anag)" , "cold drink" , "cold dessert" , "icy water" , "rough ice" .)
