內容連得起來

「各部分彼此拉著手」：拉丁字根 cohaerēre 是 con-（一起）＋ haerēre（黏住）。因為部分之間有連著，外面的人才跟得上、才會看見一個整體而不是一堆散落的片段。coherent 幾個用法的差別，只在於「拉著手的是什麼」——句子、話語，還是人。From the word’s history
Latin cohaerēre = con- ('together') + haerēre ('to stick, cling'); coherent literally describes something whose parts are clinging together.
拉丁文 cohaerēre 由 con-（一起）和 haerēre（黏住）組成，coherent 字面上就是「各部分黏著的」。現代三個用法都還在這個畫面上，只是黏著的對象不同。
