We've just released the Etruscan dictionary under the languages section. It consists of 500+ lemmata from the available Etruscan epigraphic data. The commentary might be meagre at the moment, but we will be enriching it all the time.
Avestan is a language of great historical importance. It was the language of Zoroaster and the religious scriptures produced by him. It's also the most archaic language of the Iranian subgroup of Indo-European. We have finally managed to compile a dictionary that is now available in the languages section.
