Traditional grammar

From Teflpedia

Traditional grammar (/trədɪʃənəl græmə/) or old-fashioned grammar (/ɒld fæʃənd græmə/) refers to grammar derived from grammar analysis that is based on traditional principles and nomenclature.

The traditional grammar of English was based on that of Latin since that was what early grammarians were familiar with, and possibly Aristotlean view that Latin was "closer to linguistic perfection" than English. However, the application of Latin grammar to English didn't really work.

The opposite of traditional grammar is modern grammar, but really these are a spectrum, not a dichotomy.
