Picture a small slip of paper on the outside of a box. In a few words it says what is inside and what should happen to it, so nobody has to open the box to find out. Now line those slips up in order: that queue of short entries is the other half of the word. One slip tells you what a thing is; a stack of slips tells you what is waiting and whose turn is next.
From the word’s history
The source says the origin is uncertain, and suggests it may be a small form of dock, that is, something cut short. That fits what the word always names — a very short written entry — but the packet states it as a guess, so it is offered here as a guess too.
來源資料說這個字的來歷不確定，只提出一個推測：它可能是 dock 的小稱形式，也就是「被截短的一小條」。這個推測跟它所有的意思都合得起來——docket 講的永遠是一段寫得很短的紀錄。不過來源自己標了不確定，所以這裡也只能當推測看。
