How to Use Good luck
Learner’s notesIn plain EnglishA wish that things go well for someone.
Warm and universal in the sincere sense, but a bare 'good luck' with a flat tone reads as dismissive, so speech and messages usually add a detail: good luck with the move.
Use 'good luck with' before a noun and 'good luck' plus a clause is avoided — say good luck with the exam, not good luck you pass.

Frequently Asked Questions
What is the difference between good luck and break a leg?
Break a leg is the theatre-specific version, used precisely because performers traditionally consider wishing good luck unlucky. Outside performance it sounds jokey or odd, so good luck remains the general-purpose wish.
Is it rude to say good luck?
Not in itself, but it can land badly in two situations: when someone wanted help rather than encouragement, and when the tone is flat or the request is obviously hopeless, which turns it sarcastic. Naming what you are wishing them luck with keeps it sincere.
