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]
