阻

• Topographical/Stative: Steep, rugged, or difficult to traverse (typically describing mountains, paths, or borders). This can denote a sense of remoteness or inaccessibility created by the difficulty of the terrain.
• Functional/Active: Physical obstruction (to block, dam, or wall off) or abstract opposition (to hinder progress or oppose a proposal/political move).

• Stative/Intransitive: Used to describe terrain as steep or obstructed (e.g., 阻且高 "steep and high").
• Transitive: To block or obstruct something.

• vs. 塞 (sài): While 塞 focuses on plugging a gap or closing an opening entirely, 阻 refers to the presence of an obstacle regardless of whether a gap is plugged.
• vs. 礙 (ài): 礙 suggests interference or a nuisance; 阻 generally denotes a more substantial and formidable barrier.
• vs. 障 (zhàng): Similar to 阻, but 障 often carries the additional connotation of a screen or barrier that obscures vision.
