「零件彼此黏得住」：拉丁字根 cohaerēre 就是 con-（一起）＋ haerēre（黏住），字面上是「黏在一起」。所以 coherence 說的不是每個部分好不好，而是它們之間有沒有連著——連著，你看到的就是一個完整的東西；不連，就只是一堆碎片擺在一起。From the word’s history
Latin cohaerēre = con- ('together') + haerēre ('to stick, cling'), so the modern noun still means 'the quality of clinging together'.
拉丁文 cohaerēre 是 con-（一起）＋ haerēre（黏住、附著），本義就是「黏在一起」。現代 coherence 用在文章或團體上時，說的仍然是同一件事：各部分之間有沒有黏住。
