形狀上的圓
這一支就是核心畫面本身：摸得到的弧度，沒有尖角。
adjective · B1
Having a smooth curved shape, like part of a circle or a ball, instead of sharp corners, straight edges or points.
圓弧的；圓的
核心畫面
Picture running your hand along an edge and finding no corner to catch on — the line just curves away and comes back. That is the whole word: something whose sharpness has been taken off, or that never had any. The -ed ending matters, because it hints at a shape that was given, not a shape that simply is. Once you hold that picture, the other uses are the same hand moving over different things: over a number with an awkward tail, over a person with no obvious gap, over a pair of lips closing into a circle.
可以想成用手沿著一條邊摸過去，卻找不到任何會刮到手的角：線就這樣彎過去又繞回來。整個字就是這個畫面——尖的地方被拿掉…更多收起
可以想成用手沿著一條邊摸過去，卻找不到任何會刮到手的角：線就這樣彎過去又繞回來。整個字就是這個畫面——尖的地方被拿掉了，或者本來就沒有。字尾的 -ed 有意義，它暗示這個形狀是被弄出來的，不只是本來如此。抓住這個畫面之後，其他用法就是同一隻手摸過不同的東西：摸過一個尾數難看的數字、摸過一個沒有明顯缺口的人、摸過一對收成圓形的嘴唇。Three branches
把難看的尾數磨掉
同一個動作用在數字上：4,983 的那截尾巴就像一個尖角，磨掉之後變成好拿的 5,000。
adjective · B2
Describing a number that has been changed to a simpler value close to it, such as the nearest whole number, ten, hundred or thousand.
四捨五入後的
各方面都完整
圓的東西沒有缺口也沒有突出的一角，這個畫面被借去講人和作品：哪一面都在，哪一面都不至於空掉。
adjective · B2
Having a wide range of good qualities, so that a person, an education or a piece of writing feels balanced and complete rather than strong in only one way.
全面均衡的
