Extinct language spoken in ancient Etruria (8)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
etruscan
(Other definitions for etruscan that I've seen before include "Of an ancient people of central Italy" , "from part of old Italy" , "of an ancient civilization" , "Old Italian language" , "Centaurs (anag) - from an ancient Italian country" .)
