Related: Preposition - 'Good luck' with indirect and direct objects
I'm a native english speaker, but I cannot for the life of me figure out the rules in this sentence structure. The question is about the expression "good luck". I know we have the following:
- Good luck on your exams
- Good luck with getting a job
- Good luck getting a job
- Good luck getting a date to the party
- Good luck with getting a date to the party
But I'm not sure how we decide the preposition to use. In my opinion these sentences are all correct and sound good, but I don't understand how they were made.
