On morphological internalization

Abstract

Abstract This paper deals with the creation of the Old Irish oblique relative conjunct particle -(s)aN- (e.g., dianepir “for which he says” = do-(s)aN-epir) as the outcome of the internalization of a demonstrative form used as a light head, which initially stood as a morphologically independent form. The initial step of this change was the grammaticalization of that demonstrative as the oblique element of a paradigm of relative-clause type forms in which the subject and object functions of the antecedent of the relative are also distinguished. Internalization is defined as an abrupt morphological change creating grammatical elements; its specific mechanism is the mirror image of externalization and must be distinguished from other morphological changes such as incorporation.
