Should this question be migrated from Arqade to English Language & Usage, because it asks about game terminology or not? (It asks about the difference between "Bug" and "Glitch")
Please don't. The question itself is off-topic because of the following reasons:
- There is no research the OP has done. "What is the difference between the two words?" is not workable on English Language and Usage (ELU). The Original Poster (OP) should show us his/her own research efforts and context where s(he) heard or read the two words.
Have you thoroughly searched for an answer before asking your question? Sharing your research helps everyone. Tell us what you found and why it didn’t meet your needs. This demonstrates that you’ve taken the time to try to help yourself, it saves us from reiterating obvious answers, and above all, it helps you get a more specific and relevant answer!
- We have a similar question, Is there any word for the opposite of a “bug” in programming?. We don't even know where the OP heard the two words.
ELU doesn't welcome any question without the OP's own research efforts and proper context. I think it would be better for your community to judge whether to close it or leave it open.
