Pronunciation

  • Classical: [kʷiːnˈtiː.lɪs][1]
  • Ecclesiastical: [kʷinˈtiː.lis][1]

Forms

Quīntīlis m (genitive Quīntīlis); third declension; adjective Quīntīlis, neuter Quīntīle[1][2] It is also spelled Quīnctīlis.[2][3]

Etymology

It is from Latin quīntus (“fifth”) + -īlis,[2][1] as the fifth month counted from March, the first month of the older Roman year.[3][4][1] As a noun it stands for Quīntīlis mēnsis (“the fifth month”).[1][3]

Earliest recorded meaning

Cicero dates letters by it: nōnīs Quīntīlibus vēnī in Puteolānum, “on the Nones of Quintilis I came to my villa at Puteoli”.[2]

Semantic evolution

It named the month that followed June until it was renamed Iūlius in honour of Julius Caesar,[3][4][5] in 44 BC.[1] Suetonius reports the renaming.[3] As an adjective it qualified the days of the month, as in Livy's Īdibus Quīntīlibus, on the Ides of July.[3][6]

Bede notes that July had earlier been called Quintilis from its number, and an early glossary equates the two names.[7] Old English and Old High German glosses render it.[8]

  • 81–43 BC – Cicero dates his letters by the month.[2][6][8]
  • 59 BC–AD 17 – Livy dates events to the Ides of Quintilis.[3][6][8]
