完整 (wán zhěng) is an adjective meaning 'complete' or 'intact', emphasizing that something has all its necessary parts and nothing is missing or damaged. The character 完 means 'finished' or 'entire', while 整 means 'whole', 'neat', or 'orderly'; together, they convey the idea of fullness and wholeness without gaps or defects. It’s commonly used to describe physical objects (e.g., a whole document), abstract concepts (e.g., a complete plan), or states (e.g., full recovery).

This word often appears in formal or neutral contexts — such as medical reports ('a complete recovery'), technical documentation ('a complete dataset'), or everyday speech when checking if something is undamaged or fully present. It contrasts with words like 缺失 (missing) or 残缺 (incomplete/damaged). While it can sometimes imply perfection, its core meaning is structural or functional completeness, not flawlessness.
