Pronunciation

  • Classical: [deː.noː.mɪˈnaː.tɔr][1]
  • Ecclesiastical: [de.no.miˈnaː.tor][1]

Forms

dēnōminātor m (genitive dēnōminātōris, feminine dēnōminātrīx); third declension[1]

Etymology

It is from Latin dēnōminō (“to name, designate”) + -tor, an agent noun.[2][3][4] The verb is formed from dē- and nōminō (“to name”),[4] which de Vaan lists among the derivatives of nōmen (“name”).[5]

Earliest recorded meaning

Its only ancient record is in Julian's Latin epitome of Justinian's Novels, dated 555–556 by Köbler, where it means “one who names or designates”.[2][3][6]

Semantic evolution

In Late Latin the word meant simply a person who names someone.[2][7] Medieval mathematicians used it for the number below the line in a fraction, the sense of English denominator,[1][8][4] and in medieval Polish texts it appears in the same arithmetical sense.[9]

Timeline

  • 555–556 – Julian's epitome of the Novels uses it of one who names.[2][3]
  • 1540s – English borrows it from Medieval Latin as a term of arithmetic.[4]

Meanings

Noun

  1. (Late Latin) One who names or designates.[2][6][7]
  2. (Medieval Latin, arithmetic) The denominator of a fraction.[1][8][9]
