The word 原本 is formed by combining two characters, 原 (yuán), meaning "source", "origin", or "original", and 本 (běn), meaning "root", "basis", or "fundamental". Together, they create a compound where each character reinforces and deepens the core concept of primal origin. The pairing is not a narrative sequence but a conceptual stacking, merging the idea of a primary source (原) with the idea of an underlying root or foundation (本), to powerfully express the notion of something in its earliest, most authentic, and unmodified state.
