Reconstruction:Proto-Slavic/bystrъ

Etymology
Berneker derives from and connects with a group of 🇨🇬 words with a basic meaning of “blasting forth, sallying forth” — 🇨🇬, dialectal 🇨🇬,, 🇨🇬, East Frisian 🇨🇬,. He explains the initial meaning of the Slavic as “penetrating, transparent”, which then took on different nuances in the daughter languages.

Ačaṙean adduces also 🇨🇬 as a cognate and on its basis reconstructs the meaning of the Proto-Indo-European root as “to sally forth, barge, hurtle out”.
