精明 (jīngmíng) is an adjective describing someone who is mentally sharp, perceptive, and quick to understand situations—especially in practical or financial matters. The first character 精 (jīng) conveys 'essence', 'refinement', or 'keenness', while 明 (míng) means 'bright', 'clear', or 'intelligent'. Together, they evoke the image of a mind that cuts through confusion like light piercing darkness—alert, discerning, and resourceful.

This word is commonly used to describe people in everyday contexts: businesspeople who spot opportunities early, shoppers who compare prices and quality efficiently, or elders known for wise life decisions. It carries a positive, admiring tone—unlike some English words such as 'shrewd', which can hint at cunning, 精明 in Chinese rarely implies deception; instead, it emphasizes competence, practical intelligence, and good judgment. It’s frequently paired with nouns like 人 (rén, 'person'), 老板 (lǎobǎn, 'boss'), or 主妇 (zhǔfù, 'housewife').
