Disparition de la racine verbale et généralisation de l'emploi du participele cas de l'ancienne périphrase de perfectif en diachronie

Resumen

In the history of the occidental and central dialects of Basque, the verbal periphrases composed by the verbal stem / or the participle and the auxiliaries *edin, *ezan, egin have undergone a change in the form of their principal verb. Until now, the bascologists have presented this modification as the generalization of the use of the participle within these three periphrases. Anyway, the 15th, 16th, 17th and 18th century texts� data seem to show different tendencies depending on the auxiliaries and the periods. The periphrasis based on the auxiliaries *edin and *ezan have generalized the use of the participle at different times, and the egin auxiliary based one seems to have always principally employed the participle as its lexical verb. Thus, these data give us good evidence for proposing that these three periphrases appeared and grammaticalized on the base of two different structures : (i) verbal stem + auxiliary (periphrases with the auxiliaries *edin and *ezan), (ii) participle + auxiliary (periphrasis with the auxiliary egin).
