Cultural Note

💴 The 貝 radical (shell) is ancient but very important — it appears in many money-related kanji:
Kanji Meaning Connection
貝 Shell, currency Base radical
買 To buy Using shells (money)
売 To sell Trade with money
財 Wealth, property Valuable possessions
貨 Money, goods Currency itself
This reflects how shells were once used as money in China and Japan — a beautiful example of history preserved in writing.
