‘俯首’ literally means ‘to bow the head’—‘俯’ (fǔ) means ‘to bend forward or bow down’, and ‘首’ (shǒu) means ‘head’. Together, they form a compound verb expressing the physical act of lowering one’s head, which symbolically conveys submission, humility, reverence, or quiet resignation. It is often used in formal, literary, or emotionally charged contexts—not in casual daily speech—and frequently appears in historical narratives, political discourse, or poetic descriptions.

The phrase carries strong connotations: it may describe yielding to authority (e.g., a defeated general), showing deep respect (e.g., before a teacher or elder), or expressing sorrowful acceptance (e.g., after loss). Unlike simpler verbs like ‘低头’ (dī tóu, ‘to lower one’s head’), ‘俯首’ implies intentionality, gravity, and often an emotional or moral weight behind the gesture.
