Material from English grammar earlier version
I think this could go here, but without specifically referring to English:
English grammar is a set of rules that describes and/or codifies the structural principles of the English language. While grammar is often conceived of as a set of instructions that explains how to form "proper" sentences, this is only one sense of the term. In modern linguistics, it is largely supplanted by generative grammar, which looks at the underlying deep structures the enable natural-language speakers to generate meaningful utterances, as well as by the descriptivist model, which regards actual utterances, and the variable usages of different dialects, levels of formality, and regional variation with which they are marked, as intrinsically valid, whether or not they conform to the ostensible "standard".
