Old Italian person sure can't put out (8)
I believe the answer is:
etruscan
'old italian' is the definition.
(I've seen this in another clue)
'sure can't put out' is the wordplay.
'put out' indicates anagramming the letters.
'sure'+'cant'='surecant'
'surecant' anagrammed gives 'ETRUSCAN'.
'person' acts as a link.
This may not be right. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for etruscan that I've seen before include "Sure can't refer to ancient state in Italy" , "of an ancient civilization" , "from part of old Italy" , "Early Roman" , "Ancient Italian language" .)
