From Late 中期英語 unctuous [and other forms], borrowed from Medieval Latin ūnctuōsus (“greasy, oily, unctuous”), from Latin ūnctum (“ointment; rich banquet; rich savoury dish”) + -ōsus (suffix meaning ‘full of; overly’ forming adjectives from nouns). Ūnctum is a noun use of the perfect passive participle of unguō (“to anoint; to smear with oil, to grease or oil”), from Proto-Indo-European *h₃engʷ- (“to anoint; to smear”).
unctuous (comparative more unctuous, superlative most unctuous)
