Grammar = complex consruct. CEFRL limits itself to identifying some parameters and categories which have been widely used in grammatical description. The description of grammatical organisation involves the specification of: elements (morphs, morpheme roots, etc); categories (number, case, gender, etc); classes (conjugations, declensions, etc); structures (compound and complex words, phrases, etc); processes (nominalization, affixation, etc); relations (government, concord, etc).
