Is it mom or mum? If you have seen both spellings in books, movies, social media posts or everyday conversations, you may wonder which one is correct.

If you are writing for an American audience, mom is generally the natural choice. For readers in the United Kingdom, mum is usually preferred. Understanding this regional difference can help you write naturally, avoid unnecessary spelling corrections, and recognize why people use different words for the same family relationship.
