sullen
UK: ˈsʌlən | US: ˈsʌlən
adj. 1. gloomy, morose, or ill-tempered in mood or appearance
adj. 2. dull or somber in color or tone
The word "sullen" originated in the 14th century, combining the idea of solitude ("sul") with a softening or lingering quality ("len"). Initially, it described someone who was habitually alone or withdrawn, later evolving to emphasize a brooding, gloomy demeanor. The shift from literal solitude to emotional darkness reflects how isolation was culturally associated with melancholy.
