In a science class, the meniscus is the little curve on the top of a liquid in a thin tube, made by surface tension. Water climbs the glass a bit and makes a dip in the middle (like a shallow bowl); mercury does the opposite and makes a little hill. When you read how much water is in a measuring tube, you read the bottom of that curve, with your eye level with the liquid — not the top of the glass wall.

Though actually, everyday English uses the same word much more often for a crescent-shaped piece of cartilage in the knee; footballers 'tear a meniscus'. Both uses come from the idea of a little crescent, like a young moon. This entry is the liquid one, but you will meet the knee one, and it is not a different spelling.

Though actually, everyday English uses the same word much more often for a crescent-shaped piece of cartilage in the knee;不過,日常英文更常用這個字來指膝蓋裡那塊新月形的軟骨 footballers 'tear a meniscus'.足球員常說'tear a meniscus撕裂半月板' Both uses come from the idea of a little crescent,兩種用法都來自「一小片新月」的概念 like a young moon.就像上弦月一樣 This entry is the liquid one,這個條目講的是液體那個意思 but you will meet the knee one,但你也會遇到膝蓋那個意思 and it is not a different spelling.拼法完全一樣,不是不同的字。
