Why 貝 (Shellfish) Means Money in Kanji: 買 (Buy), 員 (Member), 貸 (Lend) & 質 (Quality)
Thousands of years ago, rare cowrie shells (貝) were used as currency across East Asia. That single historical fact explains why nearly every Japanese kanji related to shopping, trade, lending, and value sits on a seashell!
Don't mistake the 貝 (Shellfish / Money) base for 見 (See)! While 見 has curved human walking legs at the bottom, 貝 has two short, symmetrical little tick legs (ハ) like a clam shell — and in kanji combinations, 貝 always means Money or Value.
