Proto-Slavic

Etymology

Perhaps from merging of:

Per Vasmer, Snoj: From *bľuti (“to surge, to gush”) +‎ *-ati, from Proto-Balto-Slavic *bljauˀtei, ultimately from Proto-Indo-European *bʰlewH-. Cognate with Lithuanian bliáuti (“to bleat, to weep”), Latvian bļaût (“to bleat”) and further akin to Ancient Greek φλύω (phlúō, “to boil over”), Latin fluō (“flow”). Related terms such as *blyjati, *blyvati can only descend from this source.
Per Trubačev (ESSJa): Specifically for the expressive meaning “to vomit, to puke”, possibly from an earlier *bjьvati, analogous to Proto-Slavic *pľьvati (“to spit”) < *pjьvati. Descendants without epenthetic *-ľ- are attested in dial. Bulgarian бю́вам (bjúvam).

Verb

*bľьvati impf[1][2][3]
