The term 'cover' typically refers to something that protects or hides an object. It can be a physical item like a book cover, a blanket, or a lid. In a broader sense, 'cover' can also mean to report on an event or to ensure a range of topics is addressed. It implies providing protection, concealment, or inclusion.
