Prescriptive

规定的

A term used by linguists to characterize any approach which attempts to lay down rules of correctness as to how language should be used. Using such criteria as purity, logic, history or literary excellence, prescriptivism aims to preserve imagined standards by insisting on norms of usage and criticizing departures from these norms.

语言学用来指任何试图对如何正确使用语言制定规则的做法。采用纯洁性、逻辑、历史或文学等标准，规定主义坚持用法规范，批评偏离规范的用法，旨在维护一些想象中的标准。
