Pronunciation

  • Classical: [aˈnoː.ma.ɫʊs][1]
  • Ecclesiastical: [aˈnɔː.ma.lus][1]

Forms

anōmalus (feminine anōmala, neuter anōmalum); first/second-declension adjective[1] The Greek-type form anōmalos (neuter anōmalon) is also used.[2][3]

Etymology

It is borrowed from Ancient Greek ἀνώμαλος (anṓmalos, “uneven, unequal”).[2][3][4][5] Köbler analyses the Greek word as the negative prefix ἀ- (a-) with a form related to ὁμός (homós, “same”).[4] The DMLBS notes that in medieval Latin it was influenced by norma (“rule”).[6]

Earliest recorded meaning

It is first found in the grammarian Diomedes, who says that genders of nouns often change in the plural and are then anomala, irregular.[7][2][4]

Semantic evolution

It remained a technical term of the grammarians, for nouns and verbs that do not follow the regular pattern, in Priscian, Probus and Martianus Capella.[7][2] The glosses render it as “unlawful” and “unlike”.[7]

In medieval Latin it was used in grammar and music for whatever departs from the rule, and more widely for something irregular or rough; as a noun it could mean an unjust person.[5][6] Aldhelm calls the verb faxo anomalous.[5][6] Niermeyer glosses it as abnormal or exceptional.[8]
