Idioms in 4 languages

“In bocca al lupo” has nothing to do with a wolf’s mouth. That is exactly what an idiom is: a phrase whose meaning never shows up in the sum of its words — and it is what separates someone studying a language from someone actually speaking it. We collected 200 of them across Italian, Spanish, French, and German, each with the word-for-word translation, what it really means, how we would say the same thing in English, and native pronunciation audio.
