Unctuous
adjective /ˈʌŋktʃʊəs/ — Luxuriously rich, oily, and smooth on the tongue.
Definition
Having a greasy or oily quality; in food contexts, having a rich, smooth, velvety texture from fat or gelatin; in human behavior, excessively and insincerely smooth or complimentary.
Beyond the definition
In food, unctuous is a compliment — slow-braised beef cheek that melts into its own gelatin, duck confit, marrow on toast. The richness is the point. When applied to people, unctuous loses its complimentary quality entirely — the excessive smoothness becomes suspicious, the pleasantness becomes a performance.
Origin & history
From Medieval Latin unctuosus (greasy), from Latin unctum (ointment), from ungere (to anoint). The root connects ointment, oil, and the religious act of anointing — all involving richness applied to a surface.
