Pronunciation

  • IPA (Classical): [ˈpɫuːs][1]
  • IPA (Ecclesiastical): [ˈplus][1]

Forms

plūs (comparative, neuter plūs); third declension[1] The Senatus consultum de Bacchanalibus has plous.[2][3]

Etymology

It is inherited from Proto-Italic *ple/o(H)is (“more”), the comparative of Proto-Indo-European *pélh₁us (“much, many”), from Proto-Indo-European *pleh₁- (“to fill”).[2][1] The many old spellings make it uncertain whether it reflects *plous- or *plois-.[2] Cognate with Old Irish lia (“more”), Ancient Greek πλέων (pléōn, “more”) and Avestan frāiiah- (“more”).[2][3]

Earliest recorded meaning

It is found in the Twelve Tables.[2] Plautus asks whether taking from great riches makes more or less.[3]

Semantic evolution

In Classical Latin it was the comparative of multus: a greater amount or number, more, with numerals more than, as Cicero's “more than once”, and something more important.[3][4] As an adverb it was to a greater degree, as Plautus' “I love no young man more”, and furthermore.[3] Plūris was at a higher price.[3]

In medieval Latin plūs minus was “more or less”.[5] English plus came into use in arithmetic in the 1570s, and its genitive gave plūrālis and English plural.[6]

Timeline

  • c. 250–184 BC – Plautus uses it.[3][7]
  • late 14th century – English plural is recorded.[6]
  • 1570s – English plus is recorded.[6]
