那根棍子，和真的那一下
這一組就是核心畫面本身，沒有比喻。一個是名詞，指那樣東西；一個是動詞，指那樣東西落下去。
noun · C1
A short, heavy stick with one end that is thicker or weighted, carried and used as a weapon.
棍棒；短棍
核心畫面
You can think of a short stick, heavy at the far end, held in one hand. No edge, no point, no aim to speak of. Everything it does comes from weight arriving somewhere. That is the picture the whole word seems to grow out of: one meaning is the stick itself, one is bringing it down on someone, and the rest move the same blunt weight into words and into the way a person pushes forward.

可以想成手裡握著一根短棍，遠端特別粗重。它沒有刀刃，沒有尖端，也談不上準頭。它能做的事，全靠那個重量落在什麼地方。bludgeon 的幾個用法，看起來都像從這個畫面長出來的：一個是那根棍子本身，一個是真的舉起來打下去，還有一個是把同樣的鈍重搬進話語和動作裡——不是打人，是壓著人、輾過人。From the word’s history
Wiktionary records bludgeon as first attested in 1730, with an uncertain origin: perhaps Cornish (written blogon around 1450), or from Middle French bougeon, a small form of bouge meaning club or stick. Both suggestions point at the same thing — a stick — which is the image the modern senses still work from.
Wiktionary 記載 bludgeon 最早出現在 1730 年，來源並不確定：一說可能來自康瓦爾語（1450 年前後寫作 blogon），一說來自中古法語 bougeon，也就是 bouge（棍子）的小稱。兩種說法指向同一樣東西——一根棍子——而那正是今天所有用法還在用的畫面。

當成比喻的棍子：不打人，壓人
這一組沒有人真的被打到，但那根棍子的三個特點全留著：很鈍、很重、一下接一下。差別只在棍子從手上搬到了話語裡，或搬到了前進的路線上。這是概念上的連結，不是在說歷史上先有哪個用法。
