The word 整体 is formed by combining two distinct characters, each contributing a core conceptual piece to create a new, unified meaning. The first character, 整 (zhěng), carries connotations of completeness, order, and putting things in proper arrangement, derived from its historical components suggesting correction and alignment. The second character, 体 (tǐ), fundamentally represents a body, form, or substance, the concrete entity itself. Therefore, the formation conceptually fuses the idea of "ordered completeness" (整) with the idea of a "tangible entity or structure" (体) to arrive at the holistic meaning of "an integrated whole", where all parts are properly assembled into a single, complete body or system.
