In bocca al lupo is an Italian idiomatic expression that translates literally to in the mouth of the wolf in English. However, it is used to mean good luck, especially in situations like exams, performances, or important life events. It is similar to saying break a leg in English.
When someone says in bocca al lupo to wish you luck, the traditional response is crepi il lupo (literally may the wolf die), which implies overcoming the challenge.
For example:
“Domani ho un esame importante.” – I have an important exam tomorrow.
“In bocca al lupo!” – Good luck!
“Crepi il lupo!” – Thanks! (literally: May the wolf die!)
The expression originally may have referred to someone facing a dangerous or challenging situation, much like being in the mouth of a wolf, but it is now used in a positive, encouraging way.
In summary, in bocca al lupo is the Italian way of saying good luck.
