‘哀号’ is a compound verb meaning 'to cry out in intense grief or anguish.' The first character, 哀 (āi), means 'grief' or 'sorrow,' and the second, 号 (háo), means 'to howl' or 'to wail'—often with vocal intensity and physical expression. Together, they evoke a raw, unrestrained vocalization of deep emotional pain, not quiet weeping but loud, plaintive crying. It often implies suffering that is overwhelming, involuntary, and deeply felt.

This word is used primarily in literary, dramatic, or descriptive contexts—not in casual daily speech. It frequently appears in narratives describing bereavement, trauma, or extreme distress (e.g., after a natural disaster or loss). While humans are common subjects, it’s also used metaphorically for animals or even personified natural elements (like wind ‘howling’ in sorrow), reinforcing its emotive, vivid quality.
