Zur Diachronie des Verbs "werden" : Vollverb - Kopula - Auxiliar

Abstract

"Werden" plays an important role in German, especially as a copula and as an auxiliary verb. It constitutes the analytic (periphrastic) part of the verbal paradigm being used as an auxiliary by encoding the categories of Tense (Future), Mood (Conditional), and Diathesis (Passive). The original meaning of PIE *uuerth- includes two basic readings – a terminative and an aterminative. Both of them have been used in the process of grammaticalisation of werden in constructions with participles and the infinitive. The terminative reading based on the feature "Change of a State" was originally the categorical marker of "werden" within the opposition "sein" vs. "werden", where "sein" indicated the meaning of "State". As a result of the further development which started in the later OHG period, the aterminative reading of "werden" in constructions with the Participle II mixed with the terminative one by establishing the Passive-Paradigm. This evolution forced "sein"+ Part. II into the periphery of the Diathesis where in NHG it is marked as a resultative (terminative) construction. On the other hand, werden + Participle I (later with Infinitive) did not establish aterminative readings due to the peculiarities of the semantics of the Participle I – form. In connection with the Infinitive the terminativity of werden developed in the process of its auxiliarisation to the prospective I prognostic reading in the future-tense perspective and to the epistemic reading in the perspective of the present tense. In the perspective of the past tense (cf. MHG "ward varen" {became ride}, "was ridden") it disappeared because in this perspective prospective or prognostic readings are impossible.
