| Definition -
A term used in modern linguistics to denote the set of linguistic concepts (e.g. the parts of speech) that Western societies inherited from the ancient Greeks and Romans. The implication is that traditional grammar is an obsolete epistemological technique that has been superseded by the science of modern linguistics.
Note: The problem is that the ideas of modern linguistics are known only to those who study it, whereas those of traditional grammar are entrenched in common discourse (e.g. many know the term parts of speech; few know universal grammar).
