齐备 (qí bèi) is an adjective meaning 'fully prepared' or 'all items present and ready for use.' The character 齐 (qí) conveys the idea of completeness, uniformity, or alignment — as in 'all together' or 'in order.' The character 备 (bèi) means 'to prepare' or 'to have on hand,' often implying readiness for a specific purpose. Together, 齐备 emphasizes that nothing is missing: every required element, tool, ingredient, or person is accounted for and available. It’s commonly used when describing setups for events, equipment for tasks, supplies for projects, or conditions needed to begin something.

This word carries a formal yet practical tone — it appears frequently in written notices, official announcements, work reports, and careful speech. Unlike more casual synonyms like 准备好了 (ready), 齐备 implies thoroughness and systematic preparation. It’s typically placed after the noun it modifies (e.g., 物资齐备) or used predicatively with 是 or 已经 (e.g., 所需材料已经齐备). It does not take aspect markers like 了 or 过, and is rarely used in isolation without context.
