An additional area of linguistics is Descriptive Linguistics. This is the practice of discovering the facts of a particular language (generally from a speaker). It is distinct from "anthropological linguistics", which is a sub-area of anthropology that looks at socio-cultural anthropological questions as realized in language, such as kinship systems, collection of terminology for material artifacts, and so on. Anthropological linguistics is the same thing as linguistic anthropology. It is also distinct from the subfields phonetics, phonology, syntax, semantics, pragmatics, morphology, lexicography and various other areas that you might try to fit language description in. For example, phonology is an area of grammatical theory that relates to sound systems and it attempts to devise a general theory of human language sound systems. Descriptive linguistics contributes to that study, but it has entirely different goals and methods. The product of a descriptive study of a language is (or should be) very different from the product of a theoretical study of the grammars of human languages.
