'Plethora' is a word that means 'a lot' or 'too many.' It's used in situations when there's too much of something, like when there are too many options to choose from, or when someone has too much of a particular item. For example, "I have a plethora of books on my bookshelf," means that there are a lot of books on the shelf. You can use it in both formal and informal situations, but it's not very common in everyday conversation.
