Boundaries and limits with 限
限 means “limit”, “boundary”, or “scope”. It is used in words establishing standards or defining limits.
Etymology
This kanji is a phono-semantic compound comprised of 阝 / 阜 (mound, embankment) as the semantic component and 艮 (a person looking back) as the phonetic component, giving the on-reading ゲン. These invoke imagery of reaching the edge of an embankment and being forced to stop there.
