The expression "spell out" means to explain something in a very clear and detailed way. It is often used when you want to make sure there is no confusion or misunderstanding. For example, a teacher might spell out the instructions for a test so that all students understand what they need to do. You can also ask someone to spell out a word if you are not sure how it is spelled. In everyday conversations, you might use "spell out" to make sure you are both on the same page about something.
