About
The character "隧" has traditionally been composed of the topographic mound radical 阝(阜) on the left, combined with the phonetic and semantic component 遂 on the right, which itself conveys a sense of proceeding or following through. This structure originally denoted a man-made path or passage cut through or into an elevated landform, such as a hill, which aligns with its core meaning of a tunnel or subterranean passage. Over time, while retaining this primary definition, the character's conceptual scope broadened slightly in certain classical contexts, influenced by the meaning of its right-hand component, to occasionally imply the act of following a path or a course of action. The modern meaning, however, remains firmly centered on the physical structure of a tunnel or an underground way.
