A more thorough explanation:

A label is a piece of writing or graphic that is put on a product or service to show where it came from. It can be a logo, title, or other marking that helps people identify the source of the item.

For example, a can of soda might have a label with the name of the brand, the flavor of the soda, and the ingredients. This helps people know what they are buying and who made it.

Labels can also be used on legal documents, like a deed or writ. In this case, a narrow slip of paper or parchment is attached to the document to hold a seal.

Overall, labels are important because they help people know what they are getting and who made it. They can also be used to make sure legal documents are authentic.
