Originally a unit of weight in ancient China (one-tenth of a 两 liǎng, roughly 3.7 g), 钱 referred to small bronze coins whose weight matched that unit. Over centuries it broadened to mean money in general. The character combines the metal radical 钅(金) on the left — signalling something made of metal — with 戋 (jiān) on the right, which historically conveyed "small" or "thin," fitting for coin-like objects.

Money talk is central to everyday Chinese conversation in a way that can surprise Western learners — asking someone how much they earn (你挣多少钱？) is often casual rather than rude. The word also appears in countless proverbs: 有钱能使鬼推磨 ("With money you can make the devil turn the millstone") reflects a pragmatic, frank attitude toward wealth. Note that 钱 refers to money in general; for specific currencies say 人民币 (RMB), 美元 (US dollars), etc. Don't confuse 钱 qián with 前 qián (front/before) — same tone and romanization, different meaning and character entirely.
