真正的樟腦丸，和真的拿去收衣服
這一組完全是字面的：那顆球本身，以及拿那顆球去收衣服的動作。核心畫面就住在這裡，後面的用法都從這裡搬出去。
noun · B2
A small ball of strong-smelling chemical that you put in with stored clothes to keep moths away from them. Usually used in the plural.
樟腦丸
核心畫面
One picture carries this whole word. It is April, the winter coats are going into a box, and you drop in a few small hard balls with a sharp smell. Nothing is being thrown away. The lid goes on, the box goes up on the shelf, and the smell stands guard while the months pass. Then one cold morning the box comes down, the coats come out, and there are no holes in them. Storing, not scrapping — and the promise of coming back — is what every use of this word is built on.
可以想成整個字都靠同一個畫面撐著。四月天，冬天的大衣要收進箱子，你丟了幾顆味道很衝的小硬球進去。沒有東西被丟掉。蓋子…更多收起
可以想成整個字都靠同一個畫面撐著。四月天，冬天的大衣要收進箱子，你丟了幾顆味道很衝的小硬球進去。沒有東西被丟掉。蓋子蓋上，箱子放上架子，那個味道就在那裡守著，一個月一個月過去。然後某個變冷的早上，箱子拿下來，大衣拿出來，上面一個洞都沒有。「是收起來，不是報廢」，還有「以後拿得回來」這個承諾——這個字的每一種用法都蓋在這上面。From the word’s history
The source records the noun as moth + ball, and says the verb comes from the noun. So the verb is not a separate word; it is the same box, the same care, applied to bigger things.
來源把名詞記成 moth（蛾）+ ball（球），並且說動詞是從名詞來的。所以動詞不是另一個字，它就是同一個箱子、同一份小心，只是拿去用在更大的東西上。

收起來不用，但留著等以後
同一個箱子，換成很大的東西：工廠、船、機器、一整個計畫。核心畫面裡那兩件事一起被帶過來了——現在不用，而且有人在顧，所以以後拿得回來。
