They’ve been deciphering eTruscan for over a century now and they have about 100 words worked out. From what I heard, they won’t be able to decipher any more until Rosetta Stone comes out with an eTruscan language program. Based on the advertisement I seen, the State Department uses that. I have no idea why the State Department would teach their envoys eTruscan, but I’m just saying.
Makes sense. Members of the US embassy staff when traveling the Tuscan countryside might encounter peasants who still speak eTruscan.
