ravis

From rāvus (“hoarse”) + -is, the first component from Proto-Italic *rawos (compare Latin raucus), of uncertain further origin. Proposed derivations include: * From Proto-Indo-European *h₃rew- (“to shout, to roar”). Cognates include Latin rūmor (“noise”), Latvian rukt (“to shout”), Proto-Slavic *řuti (“to roar”), Sanskrit रव (rava, “roaring, howling”), Avestan 𐬎𐬭𐬎𐬎𐬀𐬙𐬋 (uruuatō, “roaring”), Ancient Greek ὠρύομαι (ōrúomai, “to howl, roar”). This derivation is preferred by De Vaan, due to connecting more cleanly to cognates outside of Italic, as well as yielding a more satisfying explanation for the -a- vowel. * From earlier Proto-Indo-European *Hr̥h₁-wó-, from a root *Hreh₁- (“to shout, sound”); compare Sanskrit राय॑ति (rā́yati, “to bark”) (< Proto-Iranian *HraH-ya-) and Old Norse rámr (“hoarse”) (< Proto-Germanic *rēmaz), though these also have alternative explanations. * Onomatopoeic.
