Definition

Noun: A set of grammatical rules and principles that dictate how a language should be used, based on traditional norms, notions of correctness, and often the conventions of a prestige dialect. It is contrasted with descriptive grammar, which describes how a language is actually used by its speakers.

Usage

Prescriptive grammar provides rules that are often taught in schools and style guides. It focuses on correcting usage deemed "incorrect" or "improper."

Examples

• The rule against ending a sentence with a preposition is a well-known example of prescriptive grammar.
• Many style manuals are based on prescriptive grammar.
• The distinction between "who" and "whom" is a matter of prescriptive grammar; in everyday speech, "who" is often used for both.

Advanced Usage

• Prescriptive grammarian: A person who advocates for or formulates prescriptive rules.
  • The prescriptive grammarian insisted that the split infinitive was an error to be avoided at all costs.

Variants and Related Words

• Prescriptivism (n): The practice or advocacy of prescriptive grammar; the belief that one variety of a language is superior and should be imposed as a standard.
  • Linguistic prescriptivism often resists natural language change.
