‘吼出’ is a compound verb meaning 'to roar out'—emphasizing the forceful, loud, and often emotionally charged release of sound, feeling, or truth. The first character 吼 (hǒu) means 'to roar' or 'to shout loudly', typically associated with strong vocal intensity, like an animal’s roar or an impassioned human cry. The second character 出 (chū) adds the directional sense of 'out' or 'forth', indicating emission from within—so together, 吼出 conveys not just shouting, but bursting forth with raw power.

This word is commonly used in literary, dramatic, or expressive contexts—not everyday casual speech—to describe moments of catharsis, protest, revelation, or overwhelming emotion. It often appears with objects like 一句话 (a sentence), 真相 (the truth), 愤怒 (anger), or 声音 (a sound). While it can describe literal roaring (e.g., by a tiger), its most frequent use is metaphorical, highlighting emotional authenticity and vocal courage.
