avestan

Eg: Avestan Mithra is the Vedic Mitra, Sanskrit Asura is Avestan Ahura, Vedic divinity Varuna and the Avestan deity Ahura Mazda.

Avestan alone is insufficient evidence because despite its similarities to Sanskrit, still has many lexical differences, and the presence of a word in Avestan doesn't immediately imply it's presence in Sanskrit.

The word tiger and the identical name Tigris both come from the Avestan word tighri, which means arrow, or the more general tigra, which means sharp or pointed.

Rather, the vocabulary, grammar, and mythological content are so similar to the Avestan texts that a common linguistic origin seems inescapable.

Also, The Sanskrit sources contemporary with Avestan are in Vedic Sanskrit, which lacks that word.

The Persian for demon is div (Middle Persian dev, Old Persian daiva, Avestan daeva).

It's a bit younger than Linear B, Old Avestan and Vedic Sanskrit.

Standard or Young Avestan texts such as the Vidēvdād (Avesta, ed.

This is unlikely, as the the Vedas were composed after the Indian-Iranian split, and the last common ancestor of Avestan and Vedic is much before that.

I would argue 'Rex' is closer to Avestan (old Persian) Rastar than Sanskrit Rājati.

The chapter on Avestan is also relevant and interesting.

The regular development of PIE bh* is to Greek ph, but to b in avestan (percursor to persian), so I'd assume a borrowing.

The current Persian language "Farsi" (an Indo-European language, the oldest well-attested Indo-Iranian languages being "Vedic Sanskrit", "Avestan" etc.) is heavily soaked with 'Arabic words' (Semitic language family) through the Islamic Conquest.

There's a case to be made for Linear B because of the Greek Dark Ages, but Old Avestan?

Ancient Persian (Avestan) and Sanskrit were extremely similar to each other (basically the same language).

Reminds me of hindu soma: Soma (Sanskrit: soma) or haoma (Avestan) was a Vedic ritual drink[1] of importance among the early Indians.
