 Georges Dumézil (1898–1986), a French comparative philologist, surmised that the name of the goddess derives from Proto-Indo-European root "*h₁eu-", via the derivative form "*h₁eu-s-" which alternates with "*h₁w-es-".The former is found in Greek εὕειν "heuein", Latin "urit", "ustio" and Vedic "osathi" all conveying 'burning' and the second is found in "Vesta".
