寶

something rare or cherished

Originally a compound ideograph:

宀 (house/roof) – indicates something stored inside a house

玉 (jade) + 貝 (shells, currency) – symbols of wealth and valuables

Later, in Bronze inscriptions (金文 jinwen), 缶 (jar, vessel) was added as a phonetic element, transforming the character into a phono-semantic compound.

Thus the meaning developed into "precious treasures kept inside a house".

寶物 (보물) — treasure

珍寶 (진보) — precious treasure

寶玉 (보옥) — precious jade

國寶 (국보) — national treasure

寶劍 (보검) — treasured sword

Commonly used in personal names due to its auspicious meaning.
