可以想成一條打了死結的繩子。結還在的時候，什麼都動不了；一旦被鬆開，繩子又只是一條繩子。solve 的畫面就像那個「鬆開」——一件卡住的事、一道想不通的題擺在那裡，你找到那一拉，讓它散開。From the word’s history
English took solve from Latin solvere, 'to loosen, dissolve; untie, release, detach'. The oldest picture is not 'answer' but 'untie' — the same root sits inside dissolve and absolve, and English still calls a hard problem knotty and its answer a solution.
solve 來自拉丁文 solvere，字面是「鬆開、解開、釋放」。最早的畫面不是「回答」，而是「把結解開」；同一個字根也留在 dissolve（溶解）、absolve（免除）裡。英文到今天還說難題 knotty（打結的）、說答案 solution，走的都是這條線。
