From Proto-Indo-European *tew-, *tu- (“to swell”), with a suffix *-ro. The meaning evolution was probably: “swollen” → “fat; having a well-developed body” → “strong (animal)” → “aurochs.” Some researches believe this word to be a borrowing from Semitic into Indo-European, but many others disagree with that opinion. Cognates include Lithuanian taũras, Old Prussian tauris, Old Church Slavonic тоуръ (turŭ), Russian тур (tur, “aurochs”), Ancient Greek ταῦρος (taûros), Latin taurus (“bull”).
