About
The character "隧" is structured with the "阝" radical on the left, derived from "阜" and indicating associations with earthworks or elevations, combined with the right-hand component "遂" which primarily serves a phonetic function. Etymologically, it originally denoted a manually excavated path or roadway cut through a hill or mound, with its meaning gradually narrowing from this general sense of a passageway to the more specific modern designation for an underground tunnel. This semantic shift reflects changing technological and infrastructural contexts, where the term became specialized for subterranean passages used in transportation and mining.
