WORD OF THE DAY: UNCTUOUS
adjective | UNK-chuh-wus
Unctuous is a word that’s undergone change in recent years. It now often describes food that is fatty and oily, especially in a pleasing way. Formerly it was more typically applied as a formal adjective describing someone who is figuratively oily—that is, overly or insincerely flattering. Both uses can be found today.
// Braising chicken thighs with their skins on creates a rich, unctuous sauce that can be spooned back over the finished dish.
// The mayor’s unctuous assistant was making the rounds at the fundraiser, chatting up those known to have the biggest bank accounts.
Examples of unctuous
“The thinly sliced pork belly is shaved into curlicues and cooks up super quickly and crisply, so it’s great for an impatient group or as a first round. Thick slices are more akin to what you’d find at Korean BBQ restaurants nowadays; they’ll cook and sizzle in their own fat … resulting in juicy, unctuous bites.” — Irene Yoo, Soju Party: How to Drink (and Eat!)

Did You Know?
Unctuous is a slippery word in multiple ways. Its ultimate source is a Latin word meaning “to anoint; to smear or rub with oil or an oily substance,” and this oily character was key to the word’s meaning when it first appeared in the 14th century, as when John Trevisa wrote “Þe fruit of olyue is ful of liȝt, likynge, and vnctuous” (in modern English: “the olive fruit is bright, delicious, and unctuous”). Unctuous here means “fatty” or “oily,” as did its immediate Medieval Latin predecessor unctuosus. This same use of unctuous is quite prominent today, as the word often describes deliciously fatty foods and the sensation of such foods on the palate (as in “an unctuous mouthfeel”). But come across unctuous in literature of the 19th or 20th century and you’re more likely to see a less pleasant application, with the word describing a person or behaviour that is figuratively oily—that is, overly or insincerely flattering.
