What does gloss mean in legal terms?

In legal terms, gloss has a specific and important meaning that is different from its everyday sense of shine. A legal gloss refers to an interpretation, explanation, or commentary that has been added to a statute, constitution, or legal text by courts, judges, scholars, or long-standing practice over time. The phrase historical gloss is often used in constitutional law to refer to the meaning that has been given to a provision through historical practice and precedent. For example, if courts have consistently interpreted a clause in a certain way for decades, that interpretation becomes a gloss on the text. The term can also refer to judicial gloss, where judges add interpretive layers that clarify or effectively modify how a law is applied. In legal writing, a gloss is similar to an annotation that explains the application of a rule. The concept is important because law is not just the bare text but also includes the accumulated glosses from case law and practice. So when lawyers say there is a gloss on a statute, they mean there is an established interpretation layered on top of the literal wording that shapes how it is understood and enforced.
