箇

Phono-semantic compound:

竹 (bamboo) – semantic component, hinting that the character originally referred to something made of bamboo (a bamboo section or container);

固 (gù – solid, firm) – phonetic component, providing the sound.

In Classical Chinese, 箇 meant a bamboo segment/container, but later broadened to mean “a piece” or “an individual unit.”

In Korean Hanja, 箇 is read 개 and used in Sino-Korean words like:

箇中 (개중) – “among them”;

箇箇 (개개) – “each and every”.
