‘怒吼’ is a compound verb meaning ‘to roar with intense anger’—it vividly conveys both emotional fury and loud, forceful vocalization. The first character 怒 (nù) means ‘anger’ or ‘wrath’, carrying strong emotional weight; the second 吼 (hǒu) means ‘to roar’ or ‘to bellow’, often associated with large animals like lions or bears, but also used metaphorically for humans expressing rage. Together, they form a vivid, dramatic action word that emphasizes volume, intensity, and emotional heat.

This term is commonly used in literary, journalistic, or expressive speech—not in casual daily conversation—and appears frequently in descriptions of protests, natural disasters (e.g., roaring wind), animal behavior, or intense human outbursts. It’s more emphatic than simpler verbs like 发火 (fā huǒ, ‘to get angry’) or 大喊 (dà hǎn, ‘to shout’), and often implies loss of control or overwhelming emotion.
