In the ancient science of language ( “grammar”) studied only the native language of your scientist, but not other people’s languages; studied languages ??and prestigious intellectual culture, and living spoken language of your many people (and in some cases a lot more illiterate illiterate nations) remained outside the sphere of interest of scientists. Until the 19th century. the science of language has been prescriptive (normative), attempting not to describe the living language, spoken and provided the rules by which “should” speak (and create). Linguistics consists of observation; registration as well as a description on the facts of speech; hypotheses to explain these information; formulation of hypotheses in the kind of theories and models that describe the language; their experimental verification and refutation; prediction of verbal behavior.
