Ian itch terribly for some vino? (7)
I believe the answer is:
chianti
'some vino?' is the definition.
(Chianti is an example)
'ian itch terribly' is the wordplay.
'terribly' indicates anagramming the letters.
'ian'+'itch'='ianitch'
'ianitch' with letters rearranged gives 'CHIANTI'.
'for' acts as a link.
(Other definitions for chianti that I've seen before include "I can hit for popular Italian wine" , "Tuscan red wine" , "European wine" , "Chain it to popular Italian wine" , "Wine produced in Tuscany" .)
