The word 权限 is formed by conceptually combining two independent characters, each carrying a core meaning. The first character, 权, represents the idea of "power", "authority", or "right". The second character, 限, introduces the concept of a "limit", "boundary", or "scope". When fused, they create a single, cohesive notion meaning "the scope of authority" or "the limits within which power or rights are exercised", effectively defining the boundaries of what one is permitted to do.
