One way to hold this word: a flock of geese standing on wet grass, all cackling at the same time. Nothing is lined up, nobody is taking turns, and the noise arrives as one blur of sound. Everything gaggle does seems to grow out of that scene - the birds themselves, the call they make, and any bunch of people who crowd together and talk over one another.
gaggle 的畫面可以想成一群鵝站在濕草地上，同時嘎嘎叫。沒有隊形，也沒有人輪流開口，聲音糊成一片。這個字的幾種用法，都像是從這個場景長出來的：那群鳥本身、牠們發出的叫聲，還有任何擠在一起、你一句我一句的人。先記住那份「一團、同時出聲」的感覺，後面幾個意思就都連得起來。
From the word’s history
Wiktionary traces the word to Middle English gagelen, to cackle like a goose, and lists Icelandic gagl and Norwegian Nynorsk gagl for a goose or gosling. The sound came first, and the name for the noisy group followed it.
Wiktionary 記載這個字來自中古英語 gagelen（像鵝一樣嘎嘎叫），並列出冰島語 gagl、新挪威語 gagl 指小鵝或野雁。也就是說，先有叫聲，才有「一群一起叫的鵝」這個名字。所以吵是這個字本來就帶著的東西，不是後來才加上去的。
