可以想成一個人做事很用心、每個細節都對過，做出來的東西剛好貼合真實情況——沒有一處歪掉、也沒有靠猜。這份「因為仔細所以沒有誤差」的畫面，就是 accurate 貫穿各個用法的核心。From the word’s history
From Latin accuratus 'done with care', from ad- + cura 'care'. The idea began as 'worked on carefully' and, because careful work leaves no mistakes, shifted to 'exact, error-free' in the 1650s.
源自拉丁文 accuratus「用心做出來的」，由 ad-（朝向）加 cura（照料、用心）組成。原意是「仔細處理過的」，因為夠仔細就不會出錯，1650 年代起轉為「精確、無誤差」——正好對上今天「因用心而準確」的核心。
