Pronunciation

  • Classical: [ɪm.ma.kʊˈɫaː.tʊs][1]
  • Ecclesiastical: [im.ma.kuˈlaː.tus][1]

Forms

immaculātus (feminine immaculāta, neuter immaculātum); first/second-declension adjective[1]

Etymology

It is formed from Latin in-2 + maculātus (“spotted, stained”),[2][1][3] the past participle of maculō (“to stain”), from macula (“spot, blemish”).[3]

Earliest recorded meaning

Lucan, in the Pharsalia, speaks of Roman soil as unstained.[4][5]

Semantic evolution

The word was poetic and late:[4] after Lucan it appears in Ammianus Marcellinus and Lactantius.[4] The Vulgate has it too,[4] and in Christian and medieval Latin it meant pure and free from sin.[6][7] English immaculate, from the mid-15th century, comes from a figurative use of the Latin word, “free from moral pollution”.[3]

  • c. 390 AD – Ammianus Marcellinus uses it.[4][5]
  • 390–406 AD – The Vulgate uses it.[4][5]
  • mid-15th century – English borrows it as immaculate.[3]
