over time. As rules are established and developed, the prescriptive concept of grammatical correctness can arise. This often produces a discrepancy between contemporary usage and that which has been accepted, over time, as being standard or "correct". Linguists tend to view prescriptive grammar as having little justification beyond their authors' aesthetic tastes, although style guides may give useful advice about ''standard language employment'' based on descriptions of usage in contemporary writings of the same language. Linguistic prescriptions also form part of the explanation for variation in speech, particularly variation in the speech of an individual speaker (for example, why some speakers say "I didn't do nothing", some say "I didn't do anything", and some say one or the other depending on social context).

s to convey the same information that Chinese does with syntax. Because Latin words are quite (though not totally) self-contained, an intelligible Latin sentence can be made from elements that are arranged almost arbitrarily. Latin has a complex affixation and simple syntax, whereas Chinese has the opposite.

Education

Prescriptive grammar is taught in primary and secondary school. The term "grammar school" historically referred to a school (attached to a cathedral or monastery) that teaches Latin grammar to future priests and monks. It originally referred to a school that taught students how to read, scan, interpret, and declaim Greek and Latin poets (including Homer, Virgil, Euripides, and others). These should not be mistaken for the related, albeit distinct, modern British grammar schools. PriestleyGrammar

Recently, efforts have begun to update grammar instruction in primary and secondary education. The main focus has been to prevent the use of outdated prescriptive rules in favor of setting norms based on earlier descriptive research and to change perceptions about the relative "correctness" of prescribed standard forms in comparison to non-standard dialects. A series of metastudies have found that the explicit teaching of grammatical parts of speech and syntax has little or no effect on the improvement of student writing quality in elementary school, middle school or high school; other methods of writing instruction had far greater positive effect, including strategy instruction, collaborative writing, summary writing, process instruction, sentence combining and inquiry projects.

. In the United States, the Society for the Promotion of Good Grammar designated 4 March as National Grammar Day in 2008. Grammar instructions also differs between first-language (L1) and second-language (L2) learners, especially in academic writing. First-language (L1) are those composing in their native language, while second-language (L2) writers are writing in language they learned after childhood. Research shows that L2 learners face additional challenges when revising grammar, as they must manage both language acquisition and writing development at the same time. According to Ester Odilia Breuer, revision in L2 writing is cognitively demanding and occurs not only after writing, but also during the planning and drafting stages. She argues that L2 writers often reorganize ideas and revise structure while composing, unlike L1 writers who may rely more on intuition and automatic grammar use.
