Did You Know?
Adust comes from Latin adustus, the past participle of adūrere ("to set fire to"), a verb formed from the Latin prefix ad- and the verb ūrere ("to burn").
It entered the English language in the early 15th century as a medical term related to the four bodily humors—black bile, blood, phlegm, and yellow bile—which were believed at the time to determine a person's health and temperament.
Adust was used to describe a condition of the humors in which they supposedly became heated or combusted. Adust black bile in particular was believed to be a source of melancholy.
The association with melancholy gave rise to a sense of adust meaning "of a gloomy appearance or disposition," but that sense is now considered archaic.
