Reluctant to entertain Italian lady for a drink (10)
I believe the answer is:
chardonnay
'a drink' is the definition.
(Chardonnay is an example)
'reluctant to entertain italian lady' is the wordplay.
'reluctant' becomes 'chary'.
'to entertain' indicates putting letters inside.
'italian lady' becomes 'donna' ('lady' in Italian).
'chary' placed around 'donna' is 'CHARDONNAY'.
'for' is the link.
(Other definitions for chardonnay that I've seen before include "White wine grape" , "Variety of white wine" , "drink" .)
