Analytical construction (with the status of a word-form)
a more or less grammaticalised word combination that had been co-opted by a particular word-changing paradigm as functionally equal to the synthetic elements of the paradigm unit.
Common Germanic diachronic typological constant
consists of the gradual decay of the former inflecting, synthetic characteristics and stable tendency towards analyticism, isolation and (or) agglutination.
