dicky
noun核心畫面
For the noun you can think of a small separate piece that stands in for a bigger one, or that sits at the very back. The shirt front is only the part that shows, with a jacket hiding the fact that there is no shirt behind it. The other use is about position rather than pretending: in carriage days the dicky was the seat at the very back, and in South Asia the name stayed with the space at the back of a car.
名詞的 dicky 可以想成「一小塊單獨的東西，替整件出面」，或者「掛在最後面的那一塊」。假前襟就是前者：只做看得見…更多收起
名詞的 dicky 可以想成「一小塊單獨的東西，替整件出面」，或者「掛在最後面的那一塊」。假前襟就是前者：只做看得見的那一片，外套一蓋，沒人知道後面根本沒有襯衫。另一條線講的則是位置：馬車時代 dicky 指最後面那個座位，車子換成汽車以後，這個名字就留給了車尾的那塊空間。From the word’s history
The packet's Wiktionary etymology says the noun comes from Dicky, the pet form of Richard, and adds that in the cover and apron senses it is perhaps from dialect dick meaning a leather apron, or perhaps from Dutch dek meaning a cover. Both of those are marked as guesses in the source, so they are given here as possibilities, not as facts.
資料上說這個名詞來自 Dicky，也就是 Richard 的暱稱；另外補了一句：在「遮蓋、圍裙」這一類意思上，可能來自方言的 dick（皮圍裙），也可能來自荷蘭文的 dek（遮蓋物）。原文對後兩個說法都用了「可能」，所以這裡也只當成可能性，不寫成定論。

車子最後面的那塊空間
這一支跟「假的前襟」沒有關係，共同點只在於它也是掛在車子最後面的一塊；走的是另一條歷史路線。

You can think of dicky as the word for something that still works, but only just. A knee that holds you up until the . A lock that opens if you lift it at the same time. The picture is not of a broken thing but of a thing you have stopped trusting, and the tone is light: people use it about their own health to make the trouble sound smaller than it is.
