這個拼法底下其實是2個不同的字，意思沒有關係， 只是長得一樣。下面分開列出來。跳到 蹦蹦跳跳 · 酸豆（續隨子）
caper
v, nPicture a young goat let out into a field: it springs, lands, and springs again, for no reason except that it feels good. The feet keep leaving the ground and nothing useful is being done. Everything in this side of caper keeps that spring in it. Turn the jump into one countable movement and it is a step in a dance; let the jumping spread into behaviour and it is silly, harmless goings-on; let it grow up into something planned and risky and it becomes an adventure that the speaker still refuses to take seriously.
From the word’s history
The source says this caper is a clipping of capriole. The shortened word kept the leap and lost everything else.
字典說這個 caper 是從 capriole 縮短來的。字被剪短了，留下來的正好是那個彈跳。至於後面「胡鬧」和「勾當」的意思，是從這個畫面延伸出來的教學連結，不是字典說的歷史演變。

A second word, same spelling
caper
nPicture a small glass jar at the back of the fridge, full of hard green buds the size of peas sitting in cloudy salty water. Nothing here jumps. This caper is picked before its flower opens, and the salt or vinegar is what turns it into food; the taste is strong enough that six of them can season a whole pan of sauce.
From the word’s history
The source gives this word a separate history: from Latin capparis, from Ancient Greek kapparis. It only looks like the caper that means a leap.
字典給這個字另一條來源：拉丁文 capparis，再往前是古希臘文 kápparis。它跟「蹦蹦跳跳」的 caper 只是拼法一樣。同一個拼法底下，其實住著兩個沒有關係的字，所以這裡不必硬把它拉回那個彈跳的畫面。
