The Chinese word **烦躁 (fánzào)**, meaning "agitated" or "restless," is a compound formed through the combination of two synonymous or closely related characters to intensify and specify a meaning. The first character, **烦 (fán)**, carries the core meaning of "annoyed," "vexed," or "weary," often related to mental distress. The second character, **躁 (zào)**, means "rash," "impetuous," or "physically restless," associated with a heated, impulsive state. When combined, they create a single concept that blends the mental irritation of **烦** with the physical agitation of **躁**, resulting in a vivid description of a state of anxious, feverish impatience where one feels mentally bothered and unable to stay calm or still.
