核心畫面
One way to hold this word: your two hands closing round something and never finding a grip. The thing is fine in itself — it is the size and the shape that beat you. Keep that picture and the second use follows easily, because a rule book or a company can beat your hands in exactly the same way.

可以想成這個畫面：你兩手抱上去，卻怎麼都抓不到施力點。東西本身沒問題，是它的大小和形狀贏過了你的手。把這個畫面記住，第二個用法就很好懂了。一本厚厚的規章、一間太大的公司，也是同樣地贏過你的手。From the word’s history
From Middle English unweldy: un- plus wieldy, from wield, to have power over something and move it. Cognate forms in Old Frisian and Middle Dutch carry the sense of having no power or no mastery over a thing.
來自中古英語 unweldy，結構是 un-（不）加 wieldy，而 wieldy 來自 wield（有力量去駕馭、揮動）。古弗里斯蘭語、中古荷蘭語的同源詞都帶有「沒有力量、控制不了」的意思。所以字面上，unwieldy 就是「你駕馭不了的」，這正好是它今天兩個用法共同的底。
