Outlandish but not crazy
The study of language has generated a lot of outlandish ideas: various bits of prescriptive dogma, stereotypes and folklore about dialects, fantasy etymologies, wild theories of the origin of language. Every linguist probably has their own list. When these ideas come up in classes or conversations, I have sometimes referred to them as crazy, wacky, loony, kooky, or nutty. I’m going to try to stop doing that.
