圓
부수: 囗
획수: 13획
圓 has the meanings ‘round’ and ‘circular’.
It is used for units of currency, including the Won.

圓 = 囗 + 員
X = semantic + semantic/phonetic
• 囗 depicts a border and represents the meaning ‘to surround’. From this comes the meaning ’round’.
• 員 depicts a cauldron and represents the meaning ’round’.
Evolution:
圓 = ’round’ ➔ ’circular’ ➔ ’coin’ ➔ ’unit of money’
員 = 口 + 貝
• 口 was originally oval-shaped and was used to make the round shape of the cauldron opening more salient. This emphasises the meaning ’round’.
• 貝 is a distortion of 鼎 which depicts a cauldron.
Mnemonic
Imagine copper being melted in a round 囗 cauldron 員 to be punched into coins 圓.
