怪聲大笑
核心畫面
One way to hold this word: stand in a yard behind a hen house. The sound coming over the fence is high, loud, and chopped into short pieces — not one smooth note, but a run of sharp little cries, one after another. You cannot ignore it and you cannot mistake it for anything else. Every other use of the word is that same sound moved somewhere new: onto a person's laugh, onto a room full of pointless talk, even onto the name for a group of hyenas.

「cackle」可以想成站在雞舍後面的院子裡。從籬笆那頭傳來的聲音又高又大，而且一節一節斷開——不是順順的一長條，是一串短促尖銳的叫聲，接連不斷。這種聲音你沒辦法忽略，也不會認錯。這個字後來的每一種用法，都是把同一串聲音搬到別的地方：搬到人的笑聲上、搬到一屋子沒重點的話上，甚至搬去當一群鬣狗的名字。From the word’s history
The word comes from Middle English caclen, and is probably imitative — the word was built to copy the noise itself. Its relatives do the same job: Dutch kakelen, German gackern, Danish kagle.
這個字來自中古英文 caclen，很可能是模仿聲音造出來的：字的發音本身就在學那個叫聲。它在別的語言裡的親戚也是同一招，像荷蘭文 kakelen、德文 gackern、丹麥文 kagle。
