The word 完全 is formed through the semantic compounding of two independent characters, 完 (wán), meaning "whole" or "to finish", and 全 (quán), meaning "entire" or "complete". These two synonyms are combined not to create a new grammatical pattern, but to conceptually reinforce and blend their overlapping meanings. The fusion results in a single, cohesive concept of "complete" or "total", where the sense of entirety from 全 merges with the sense of wholeness or perfection from 完, forming a unified idea stronger than either character alone.
