pelt
verb核心畫面
One way to hold this pelt: things going out one after another and landing hard on the same spot. Not one throw, but a stream of them — snowballs, stones, hail, questions — arriving faster than anyone can move out of the way. What matters in the picture is not aim but the fact that it keeps coming. And when the force belongs to the person rather than to the thing thrown, the same energy shows up in the feet: someone tearing down a street at top speed.

可以想成一樣接一樣的東西被用力丟出去，砰砰砰落在同一個地方。畫面裡最重要的不是丟得準不準，而是「一直來、躲不掉」。雪球是這樣，冰雹是這樣，一連串的問題也是這樣。而當那股勁不在丟出去的東西上、改成長在人自己身上，就變成腳步的速度：一個人往前衝到最快。From the word’s history
Wiktionary's etymology 2 traces this pelt to Late Middle English pelt/pelte, probably a variant of pilten (to push, thrust, strike), possibly going back to Latin pultāre (to beat, knock, strike), the frequentative of pellere (to drive, push, hurl). A frequentative verb means repeated action, which fits the one-after-another picture.
依照 Wiktionary 的第二條詞源，這個 pelt 來自晚期中古英語 pelt／pelte，可能是 pilten（推、刺、打）的變體，再往前可能接到拉丁文 pultāre「敲打」，而 pultāre 又是 pellere（驅、推、擲）的反覆型。「反覆」這一點正好對上它今天「一下接一下」的畫面。

One way to hold this pelt: a whole animal skin with the fur still on it, spread out so you can almost see the shape of the animal in it. It is not the smooth, treated material we call leather — the hair is still there, thick and warm under your hand. Look from that skin toward a living animal and you get the coat it is wearing; look toward the person handling it and you get the act of taking that skin off.

可以想成一整張帶著毛的動物皮，攤開來還看得出動物的形狀。重點不是處理過、光滑的皮革，而是毛還在、摸起來蓬鬆溫暖的那一面。從這張皮往活著的動物看，就是牠身上那層毛；往人的動作看，就是把這張皮取下來。From the word’s history
Wiktionary's etymology 1 gives Middle English pelt (the skin of a sheep), possibly through Anglo-Norman pelette and Old French pel, from Latin pellis (animal skin, hide, leather, a garment made of animal skin). The same root shows up in pelisse, a fur coat.
依照 Wiktionary 的第一條詞源，這個 pelt 來自中古英語 pelt（羊皮），可能經由盎格魯諾曼語 pelette 和古法文 pel，再往前是拉丁文 pellis「獸皮、皮革、獸皮做的衣服」。同一條線上還有 pelisse（毛皮外衣）。所以「一張皮」這個畫面從頭到現在都沒變過。
