One might call it Hellenic (6)
I believe the answer is:
greece
'one might call' is the definition.
Although both the answer and definition are singular nouns, I cannot see how they can define each other.
'it hellenic' is the wordplay.
I cannot quite see how this works, but
'it' could be 'e' ('e' can mean 'electronic' which is similar to 'IT') and 'e' is present in the answer.
The remaining letters 'grece' is a valid word which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for greece that I've seen before include "Republic whose mythology is widely known" , "The country sounds slippery" , "Country of southern Europe" , "Bust area" , "Hellas is its ancient and modern name" .)
