The word "狭隘" is formed by combining two characters with similar meanings: "狭" means narrow, constructed from the radical "犭" (dog, often suggesting constriction) and the component "夹" (jiā) primarily for phonetic indication, while "隘" also means narrow, constructed from the radical "阝" (terrain, indicating a narrow pass) and the component "益" (yì) primarily for phonetic indication; together, they emphasize the concept of narrowness, extending it metaphorically to denote narrow-mindedness or intolerance.
