Where it comes from

1. Proto-Indo-European*smh₂-tló-m“wiping (?)”
2. Latinimmaculātus“unstained”
3. Middle Englishimmaculat
4. Englishimmaculate

From Late Middle English immaculat, immaculate (“blameless; flawless, spotless; specifically of the Virgin Mary: pure, undefiled”), borrowed from Latin immaculātus (“unstained”), from im- (negative prefix) + maculātus (“stained, spotted; defiled, polluted; (figurative) dishonoured”), the perfect passive participle of maculō (“to spot, stain; to defile, pollute; (figurative) to dishonour”), from macula (“a blemish, spot, stain; (figurative) blot on one’s character, fault”), ultimately from Proto-Indo-European *smh₂-tló-m (“wiping (?)”), from *smeh₂- (“to rub; to smear”). The word displaced Middle English unwemmed (“pure, untainted”). See also -ate (adjective-forming suffix). By surface analysis, im- + macule + -ate. Cognates * Catalan immaculat * Italian immacolato, immaculato (obsolete) * Middle French immaculé (modern French immaculé) * Portuguese imaculado * Spanish inmaculado
