bʾlk'

Nyberg connects with the root *bar- (“to bring, carry”), which in some descendants has the meaning “to ride”, ultimately from Proto-Indo-European *bʰer-.

On the other hand, Ałayan derives from the homonymous root *bar- (“to move rapidly, to storm”) (in Cheung *barH-), on which see Cheung and Bartholomae. From the initial unattested meaning “fast-moving” the senses “steed” and—in the Armenian and Turkic borrowings—“hunting dog” can be easily explained.

Cognate with Manichaean Middle Persian bʾrg (bārag, “horse, mount”), Manichaean Parthian bʾrg‎ (bārag, “horse, mount”).
