The word "sulking" refers to the act of being quietly angry or upset, usually to express displeasure or resentment. When someone is sulking, they often withdraw from social interaction, can be silent, and may show a gloomy or moody demeanor. This behavior is typically seen as a way to seek attention or sympathy from others, particularly in children or adolescents.
The word "sulk" originates from the early 16th century, reflecting a sense of being sullen or gloomy. It comes from the Middle English word "sulken," which likely is related to the Old Norse word "sulka," meaning to sulk or frown.
