The word 暴躁 is formed by combining two characters, each contributing a layer of meaning to paint a vivid picture of a specific temperament. The first character, 暴, depicts a sudden, violent, and intense outburst, like the sun beating down (as in its related meaning of "exposure") or an explosive flare-up. The second, 躁, is built from the "foot" radical and signifies a state of restless, agitated, and frantic physical movement or mental impatience. When fused, they create a compound where 暴 provides the explosive "heat" and intensity of the emotion, and 躁 supplies the restless, impulsive, and uncontrollable "motion", together perfectly encapsulating the concept of a hot-tempered, irritable, and violently impatient disposition.
