Grammar schema

From Teflpedia

A grammar schema plural (plural: grammar schemata) is a consistent description of a language's grammar.

Unfortunately, one schema may not be consistent with another, leading to potential terminological ambiguity due to overlap and exclusion, misleading terminology, multiple terms for one thing, oversimplified pedagogic grammar but overcomplicated scientific grammar, etc.

Worse, at least some of this has to be taught to students.
