Prescriptive (definition)
From Scottish Gaelic Grammar Wiki
Prescriptive Rules are designed to impose a correct usage of grammar for a language. These rules are usually written by so-called experts and have little linguistic value or accuracy. An example of a prescriptive rule is the prohibition of ending a sentence with a preposition. Prescriptive rules are contrasted with descriptive rules, which describes native speaker's actual usage.
