'被俘' is a two-character verb meaning 'to be captured', used exclusively in the passive voice. The first character 被 (bèi) is the standard passive marker in Chinese, indicating that the subject undergoes an action done by someone else. The second character 俘 (fú) means 'to capture' or 'prisoner', derived from military and historical contexts where people or animals are taken by force. Together, 被俘 functions as a fixed passive verb phrase — it cannot be split, and no object follows directly after it.

This term appears most often in historical narratives, war reports, wildlife conservation discussions, or news about endangered species being seized illegally. While it can technically apply to humans or animals, in modern usage it’s frequently used for animals — especially when describing poaching, illegal trafficking, or rescue operations involving protected wildlife. It carries a formal, slightly solemn tone and is rarely used in casual speech.
