Prescriptive

Linguistic prescription (or prescriptivism) is the practice of elevating one variety or manner of language use over another. It may imply that some forms are incorrect, improper, or illogical, or lack communicative effect, or are of low aesthetic value. Sometimes informed by linguistic purism, these normative practices may address such linguistic aspects as spelling, grammar, semantics, pronunciation, and syntax. They may also include judgments on socially proper and politically correct language use.

Linguistic prescriptivism may aim to establish a standard language, teach what a particular society perceives as a correct form, or advise on effective communication. If usage preferences are conservative, prescription might appear resistant to language change; if radical, it may produce neologisms.

Prescriptive approaches to language are often contrasted with descriptive linguistics ("descriptivism"), which observes and records how language is actually used. The basis of linguistic research is text (corpus) analysis and field study, both of which are descriptive activities. Description, however, may include researchers' observations of their own language usage.

Despite being apparent opposites, prescription and description may inform each other, as comprehensive descriptive accounts must take speaker preferences into account, and an understanding of how language is actually used is necessary for prescription to be effective.

The chief aim of linguistic prescription is to specify standard language forms (either generally, as in Standard English, or in style and register) in a way that is easily taught and learned. Prescription may apply to most aspects of language, including spelling, grammar, semantics, pronunciation, syntax, and register.
