I want to know the answer to the following question:
What language is Carduchi thought to have become?
All the background I'm provided with is that "In addition to Old Persian and Avestan, which are the only directly attested Old Iranian languages, all Middle Iranian languages must have had a predecessor "Old Iranian" form of that language, and thus can all be said to have had an (at least hypothetical) "Old" form.". Is that enough to answer the question?
