वृ

• (Vedic) IPA^(key): /ʋr̩/
• (Classical) IPA^(key): /ʋr̩/

From Proto-Indo-European *h₂wer- (“to cover”), and related to Latin operiō (“to cover, shut”), Lithuanian suvérti (“to shut”).[1]

Older theories derived the root from Proto-Indo-Aryan *war-, from Proto-Indo-Iranian *war-, from Proto-Indo-European *wer- (“to cover, envelop”), and connected the root to Scottish Gaelic fearann (“estate, land”), Avestan 𐬎𐬀𐬭𐬛𐬥𐬁 (uardnā, “cover, envelope”). Other theories connected the root to Proto-Indo-European *welH- (“to turn, wind, coil”).[2] These two Indo-European roots may have semantically influenced and merged with the Sanskrit (though Mayrhofer and Rix seem to reconstruct the *welH- as *wel- instead).[3]
