霸 is a noun referring to someone or something that dominates by force or influence — a tyrant, a bully, or a hegemonic power. In Chinese the word often carries negative overtones of raw power and coercion. It also appears as a productive root in compounds like 霸权 (hegemony), 霸道 (overbearing), and 恶霸 (local bully). Although the original dictionary gloss includes verb meanings (dominate, lord over), 霸 is strictly a noun here; the verbal sense is expressed by words like 霸占 or 称霸.
