Pronunciation

  • Classical: [ˈwɔ.mɪ.tʊs][1]

Forms

vomitus m (genitive vomitūs); fourth declension[1]

Etymology

It is from Latin vomō (“to vomit”) + -tus, with the suffix of action nouns.[2][1] The verb goes back to Proto-Italic *weme/o- and Proto-Indo-European *wemh₁- (“to vomit”).[3][1]

Earliest recorded meaning

It is found from Plautus on,[3][4] meaning the act of vomiting; in the Rudens he has pulmōneum vomitum vomere, to vomit up one's lungs.[5][6]

Semantic evolution

Besides the act of vomiting, it came to mean the matter vomited, as in Celsus and Pliny the Elder.[2][5] Lucilius and Plautus also used it as a term of abuse for a disgusting person.[5][6]

Timeline

  • c. 250–184 BC – Plautus uses it for vomiting.[2][4]
  • c. 180–102 BC – Lucilius uses it as a term of abuse.[5][4]
  • 14–37 AD – Celsus uses the plural for green and black vomit.[2][5][4]
  • 23/24–79 AD – Pliny the Elder uses it for vomited matter.[5][4]

Meanings

Noun

  1. The act of vomiting.[2][5]
  2. Vomited matter, vomit.[2][5]
  3. (term of abuse) A disgusting person.[5][6]

Usage notes

Vomitus, -a, -um is also the perfect passive participle of vomō, which Gaffiot lists as a separate headword.[6]
