You can think of quibble as someone stopping the whole cart for a . The big thing is basically fine; the argument is about one small piece of it, very often the exact words. The word carries the size of the point and the speaker's opinion of it at the same time.
quibble 可以想成「為了一顆小石頭，把整台車停下來」。大方向其實沒問題，卡住的是其中一個很小的地方，而且很常是「用字」。這個字一次說了兩件事：爭的點很小，說話的人也覺得不值得。正因為它自帶這層評價，英文常拿它來先替自己打預防針——先說這是 quibble，再把小意見說出來。
From the word’s history
Origin uncertain. One account is quib plus the small-thing ending -le, with quib probably from Latin quibus, a word that filled old legal papers and came to suggest fussy, word-picking argument.
來源不確定。一個說法是 quib 加上表示「小」的字尾 -le；而 quib 可能來自拉丁文 quibus，那是舊法律文件裡滿滿都是的字，久了就讓人聯想到咬文嚼字、纏著細節的講法。可以想成：字尾的「小」和法律文件的「摳字眼」，剛好就是今天這個字的兩個成分。
