Annotation is a way for developers to add metadata or supplementary information to their code without affecting its execution. It's like leaving sticky notes all over your codebase - helpful for you and others, but ultimately ignored by the compiler or interpreter.

How to use it in a sentence

• "I spent all day adding annotations to my Python code, and now it looks like a Jackson Pollock painting."

• "Our lead architect is obsessed with annotations. I think he dreams in @Override and @Deprecated."
