整体 (zhěngtǐ) literally combines 整 (zhěng), meaning 'whole', 'complete', or 'entire', and 体 (tǐ), meaning 'body' or 'entity'. Together, they form a compound meaning 'the whole', 'the entirety', or 'the holistic entity' — emphasizing unity and interdependence rather than isolated parts. It’s commonly used in contexts where one must consider something as a unified system, such as in traditional Chinese medicine (where health is viewed holistically), education, design, or management.

This word functions primarily as a noun ('the whole') but also frequently as an adjective modifying nouns (e.g., 整体规划 — 'comprehensive plan'). It carries a formal, slightly academic register and appears often in written language, official reports, and professional discourse. Unlike colloquial terms like 全部 (quánbù) or 所有 (suǒyǒu), which simply mean 'all', 整体 stresses structural coherence and functional integration — the idea that the parts only make sense within the larger framework.
