رخش

Ultimately from Proto-Iranian *ra(n)ǰ- (“to colour, dye”) (compare Sogdian [script needed] (rɣš- /⁠raxš⁠/, “Rakhsh”), Khwarezmian رختک‎ (rxtk /⁠raxtak⁠/, “red”), Mazanderani رش‎ (raš, “red (of cattle)”), Northern Kurdish reş (“black”), Talysh رش‎ (rəş, “light brown”)), from Proto-Indo-Iranian (compare Sanskrit रञ्ज् (rañj, “to be dyed or coloured, to redden, grow red, glow”)), from Proto-Indo-European *reg- (“to dye”).

The Persian word is not inherited but is borrowed probably from the Sogdian cognate.

Akin to Old Armenian երաշխ (erašx), an Iranian borrowing.
