sulkiness

Sulkiness is a state of gloomy resentment, usually shown through silence, withdrawal, or a sullen expression. It's more than simple sadness. It often includes hurt feelings, resentment, and a sense of being ignored, disappointed, or misunderstood. Think of a character in a novel who turns away from others after a small insult or a disappointment. That is sulkiness in action.

The word suggests that the unhappiness is visible in silence and body language, even if the person says very little. It is not simply feeling low. It is a way of showing displeasure without speaking openly about the problem. A child might show sulkiness by refusing to speak or join in, while an adult might become quiet, distant, and hard to talk to.

Sulkiness often grows out of disappointment, frustration, jealousy, or feeling ignored. A short spell of sulkiness is common, but if it happens often or lasts a long time, it can point to a deeper problem in the person's mood or relationships.

You will often see it described with words like "brooding," "sullen," and "resentful." A writer might describe a character as "full of sulkiness" after an argument, or note that the whole room could feel his sulkiness. It is a quiet but noticeable kind of negativity.
