prescriptive

This term carries a tone of authority and rigidity, often implying a top-down imposition of standards. It is frequently used in a critical or academic sense to describe systems that prioritize "how things should be" over "how things actually are." In professional settings, it suggests a lack of flexibility, where strict adherence to a manual or code is mandatory.

In linguistics, the word creates a sharp contrast with descriptive. While a descriptive approach observes natural language patterns, a prescriptive approach dictates the "correct" way to speak or write, often based on traditional or arbitrary rules. This distinction is central to debates about language evolution and social class.
