Pronunciation

  • IPA (Classical): [reː.ɡʊˈɫaː.rɪs][1]
  • IPA (Ecclesiastical): [re.ɡuˈlaː.ris][1]

Forms

rēgulāris (neuter rēgulāre, adverb rēgulāriter); third-declension two-termination adjective[1]

Etymology

It is from Latin regula (“ruler, bar, rule”) + -āris.[2][1] rēgula comes from regō, from Proto-Indo-European *h₃reǵ- (“to straighten, direct”).[1][3]

Earliest recorded meaning

Pliny the Elder uses aes rēgulāre, a refined copper that can be beaten into bars.[2][4] Köbler dates him 23/24–79 AD.[5]

Semantic evolution

In Pliny it meant of a bar, malleable, and Isidore of Seville repeats the term.[4][6] The TLL notes that it is otherwise found from Tyconius on, above all in Christian writers.[7] Caelius Aurelianus uses it of books containing rules of diet, and Cassiodorus of what is canonical.[8][6]

In medieval Latin it meant regular, normal, and conforming to the rules of church discipline, living under a monastic rule.[9][5] As a noun rēgulāris was a monk or canon, from 755, and a nun.[5] English regular is recorded around 1400 for what belongs to a religious rule.[3]
