Pronunciation

  • Classical: [ae̯.mʊˈɫaː.tʊs], [ae̯.mʊˈɫaː.tuːs][1]
  • Ecclesiastical: [e.muˈlaː.tus], [e.muˈlaː.tus][1]

Forms

aemulātus m (genitive aemulātūs); fourth declension[1]

Etymology

It is a fourth-declension action noun from Latin aemulor (“to rival, emulate”), with the suffix -tus.[2][3][4] The verb is formed from aemulus (“rival”), which de Vaan explains as a diminutive of a noun “imitation” that goes back to Proto-Italic *aimo- and Proto-Indo-European *h₂ei-mo- (“imitation”).[5]

Earliest recorded meaning

It is a word of Tacitus:[6][7] in the Annals Otho is sent to govern Lusitania so that he should not play the rival in Rome (aemulatus ageret).[3][8]

Semantic evolution

L&S thinks it is perhaps only Tacitean, beside the usual Classical aemulātiō.[6] Besides the Annals passage, it stands in the Histories, where Lipsius restored aemulatu, and Heinsius conjectured it in the Agricola, where other editors read similitudine.[6][3] Georges gives it the sense of jealousy and envy,[9] and Conte of rivalry and envy.[8]

Timeline

  • 98–115 AD – Tacitus uses it in the Annals and, as Lipsius reads it, in the Histories.[6][3][7]

Meanings

Noun

  1. Rivalry, emulation.[2][6]
  2. Jealousy, envy.[9][8]

Usage notes

Aemulātus is also the perfect participle of aemulor.[10]
