Artikulu honetan finkatu eta erakutsi dugu hiru kasuko ASM(NDE), /i/
duena, edin aditzari dagokiola. Hiru kasuko aditz laguntzaile gisa erabiltzen
hasi zen hegoaldeko goi nafarreran, eta zehazki Iruñerrian. Hortik gaur egun
hartzen duen lurralde osora zabaldu zen, komunikabide nagusien bidez,
Bidasoa ibarrean barna Iruña eta Irun lotzen dituen bide ertzetan. -diantzinako
erroa lehenaldiaren zenbait bariazio dialektaletan agertzen da
oraindik. Orainaldian bokalen arteko /d/ galdu, eta gelditzen den [ai]
diptongoa /i/ bilakatu zen. Halaber, hiru kasuko ASM(NDE) honen
ergatiboaren 3. pertsonaren flexioetatik dator edin aditz laguntzaile beraren bi
kasuko ASM(ND) intransitiboa. Honek ere [ai] diptongoa erakusten du
erregulartasunez, eta izan aditzaren ASM(ND) iragangaitza -bi kasu dituenaordezkatu
du. Geroago, z- aurrizki berriak ordezkatu zuen d- jatorrizko 3.
pertsonaren aurrizkia, euskalki guztietan Uharte Arakilen izan ezik, bertan daurrizkiak
iraun baitu. Hiru kasuko edin aditzaren ASM(NDE)an, [ai]
diptongoa /i/ bilakatu zen, CF = ai > i bilakaerari jarraiki. Geroago, berdin
gertatu zen Oiartzungo bi kasuko ASM(ND, edin) iragangaitzean. Hala ere,
zenbait herritan antzinako [ai] diptongoak iraun du hiru kasuko
ASM(NDE)an.
In the present article, we have determined and demonstrated that the tricasual
Verbal Morphological Structure (NDE) with /i/ belongs to the verb edin
(to get), use of which as a trivalent auxiliary verb began in the Southern
Navarrese dialect, and more specifically in the Pamplona area, from whence
it spread to the rest of the territory in which it is now used via the main routes
of communication, along the corridor which joins Pamplona with Irun
through the Valley of Bidasoa. The old root -di- still appears in some dia -
lectal variants of the past. The intervocalic /d/ was lost in the present and the
resulting diphthong [ai] was reduced to /i/. In turn, the intransitive bicasual
VMS(ND) of the auxiliary verb edin itself, which presents the diphthong [ai]
in an equally regular manner, having substituted the intransitive bicasual
VMS(ND) of izan, comes from the 3rd person ergative inflections of this tricasual
VMS(NDE) of edin. Later, the original 3rd person prefix d- was
replaced by the new prefix z- in all the dialects except in Uharte Arakil, where
d- has been preserved. The diphthong [ai] was reduced to /i/ by the PC = ai
> i in the tricasual VMS(NDE) of edin and, at a later stage, in Oiartzun’s new
intransitive bicasual VMS(ND, edin), as well. The old diphthong [ai] has,
however, been preserved in the tricasual VMS(NDE) in some localities
