Doomsday is a word that describes a very bad or catastrophic event, usually something that would cause the end of the world or the end of some important aspect of our lives. We typically use it to talk about fictional scenarios or predictions related to wars, natural disasters, diseases, and other things that would fundamentally change the way we live. It's not a word that is used in everyday conversation, but may be seen or heard in news stories or movies.
