権限
けんげん · kengen · JLPT N1 · noun
authority
🔑 権 (right/weight) + 限 (limit): the power you hold has a set limit
権 means right or authority, and 限 means limit or boundary. Together, 権限 is the scope of power you are allowed to use, or jurisdiction over a domain.
限 — mound radical 阝 + 艮 (phonetic)
限 combines the 阝 (mound/hill) radical on the left with 艮 on the right, which provides the sound. The mound element suggests a boundary or barrier formed by terrain, and the character came to mean 'limit' or 'boundary' — the edge one cannot cross.
