prescriptive rule

[/prɪˈskrɪptɪv ruːl/]
nounpl: prescriptive rules
regra prescritiva
1. A rule that dictates how language should be used according to established standards, norms, or conventions, often based on tradition or authority rather than actual usage
The prescriptive rule against ending sentences with prepositions is widely taught in schools, though modern linguists often ignore it.
A regra prescritiva contra terminar frases com preposições é amplamente ensinada nas escolas, embora linguistas modernos frequentemente a ignorem.
2. In linguistics, a normative guideline that specifies correct or incorrect language use, as opposed to describing how language is actually used
According to prescriptive rules, one should say 'It is I' rather than 'It is me,' even though the latter is more common in everyday speech.
De acordo com regras prescritivas, deve-se dizer 'Sou eu' em vez de 'É eu', embora a última forma seja mais comum na fala cotidiana.
Prescriptive rules are deeply rooted in traditional language education in both Brazil and the USA. In Brazil, prescriptive grammar is heavily emphasized in schools and formal contexts, reflecting Portuguese colonial educational traditions. In American English, there is ongoing tension between prescriptive rules (taught in schools) and descriptive linguistics (used by modern linguists). The debate between prescriptivism and descriptivism reflects broader cultural attitudes toward language authority, standardization, and social class distinctions.
