In language, there are no rules. There are agreements.
To speak of language as having “rules” implies some sort of official authority. But, as it has been said, language is humanity’s greatest invention, and its most democratic. There are no officials. There is no authority. What we call “rules” are simply “agreements” that enable individuals to communicate across the great gulf of space between us. We agree that this object I am sitting on is a “chair.” You don’t have to abide by the agreement, and you can call it a “customer service representative,” but communication will be impeded.
