Pronunciation

  • Classical: [ˈwɔ.moː][1]
  • Ecclesiastical: [ˈvɔː.mo][1]

Forms

vomō (present infinitive vomere, perfect active vomuī, supine vomitum); third conjugation[1]

Etymology

It is inherited from Proto-Italic *weme/o-, inherited from Proto-Indo-European *uemh1- (“to vomit”); the old root present was made thematic in Latin.[2] Cognate with Sanskrit वमिति (vámiti, “vomits”), Ancient Greek ἐμέω (eméō, “to vomit”) and Lithuanian vémti (“to vomit”).[2][3]

Earliest recorded meaning

De Vaan dates it from Plautus,[2] whose Casina has “go away, unless you want me to be sick today!”.[3] Ennius already has the Tiber pouring into the salt sea.[3]

Semantic evolution

It means “to vomit, be sick”, and transitively to throw up food or blood, as Virgil's bull vomiting blood mixed with foam.[3][4] Lewis and Short note vomiting as a common Roman way of renewing the appetite.[4] Of things it is “to pour or belch out”, of rivers into the sea and of Etna's fire.[3][1]

Church Latin glosses it “vomit”.[5]

Timeline

  • c. 250–184 BC – Plautus of being sick.[3][2][6]
  • 204–169 BC – Ennius of the Tiber pouring into the sea.[3][6]
