One way to hold this word: a gate opens, something springs out through it, and the gate is still there to come back to. That is the whole shape — out, quickly, from somewhere you still hold. Change what springs out and you get every meaning on this page: soldiers through a town gate, a bird off a branch, a joke out of a quiet person, a walker out of the front door on a rainy morning.
可以想成一扇門打開，有東西從裡面一躍而出，而那扇門還在原地等著它回來。整個字的形狀就是這樣：從一個你仍然守著的地方，快速地出去。把「躍出去的東西」換掉，這一頁的每個意思就都有了——出城的守軍、離枝抓蟲的小鳥、從安靜的人口中射出的一句笑話，還有下雨早晨推開大門出門的那個人。
From the word’s history
Sally came into English from French saillie, from saillir, to leap forth, and before that from Latin salire, to leap. The leap is still doing all the work in every modern use.
sally 是從法文 saillie 借進英文的，saillie 來自動詞 saillir（躍出），再往上是拉丁文 salīre（跳）。今天每一個用法，其實都還在用這個「跳出去」的動作：守軍跳出城門、鳥跳離樹枝、一句話跳出安靜的場面。
