ChiramiWhy the kanji for treasure is a jewel under a roof (宝)
The kanji for treasure is 宝 (takara). It has two parts: 宀, a roof, and 玉, a jewel, underneath. Something precious, kept safe under your own roof: that’s treasure.
What the kanji say
宀 is the roof radical, a house seen from the side; the dot on top looks like a little chimney. It’s the same roof as in 家 (ie), a house, and 安心 (anshin), peace of mind.
玉 (tama) is a jewel, especially jade, and also a ball. It began either as a jade ritual object or as pieces of jade strung on a cord. Early on it looked just like 王 (ou), king, so a dot was added to tell the two apart.
Where it really comes from
The roof and the jewel really are the heart of it. On oracle bones more than 3,000 years old, treasure was written as a house with jade and cowrie shells inside it: treasures in a house. Cowrie shells were used as money, which is why 貝, shell, also turns up in kanji like 買う (kau), to buy.
Later, in bronze inscriptions, 缶, a clay jar, was added to show the pronunciation. That gave the full traditional form, 寶: a roof, with jade, a jar and a shell underneath it. Traditional Chinese still writes it that way. Japanese, like simplified Chinese, uses the short form 宝, which keeps just the roof and the jewel.
So the video’s picture is the shortened version, and it happens to be the core of the oldest one.
