Forms
onctueux (feminine onctueuse, masculine plural onctueux, feminine plural onctueuses)[1] Old French unctuose (feminine, second half of the 13th century), Middle French unctueus (1314); onctueux from the 14th century.[2][3][4]
Etymology
It is borrowed from Medieval Latin unctuōsus (recorded in 1250),[2][5][3][6] from unctum, the supine of unguō (“to anoint”).[2][5][1] It belongs with onction and oindre.[5][7]
Earliest recorded meaning
It is first found in the second half of the 13th century in an introduction to astronomy, in savor unctuose “an oily taste”.[2][5]
Semantic evolution
In 1314 the surgeon Henri de Mondeville used unctueus for what is fit for anointing, and of grease, which he called more unctuous and moister than tallow.[2][7] The adjective describes what feels soft and smooth to the touch, by comparison with a fatty substance.[5]
From the 18th century, like onction, it was used figuratively for gentle, moving language (1741) and for a person (1763), and since the 19th century often with a pejorative sense of affected, oily sweetness (1863, Goncourt).[2][5]
