Diacronía de los resultados secundarios del diptongo /ue/ en judeoespañol

Judeo-Spanish presents some surprising results as regards the secondary evolution of the diphthong /ˈue/. Contrary to Spanish <i>jueves</i> ‘Thursday’, <i>tuerto</i> ‘one-eyed’, <i>sueño</i> ‘dream’, <i>nuera</i> ‘daughter-in-law’, Judeo-Spanish has <i>ĵugüeves</i>, <i>tugüerto</i>, <i>(e)sfueño</i>, and <i>elmuera</i>. That is, /ˈue/ has evolved either into /u.ˈgue/, it has developed a fricative before the diphthong (/ˈsue/ &gt; /s.ˈfue/), or labialized the previous nasal (/ˈnue/ &gt; /ˈmue/).In this study we present an explanation for this phenomenon that combines the regular Ibero-Romance phonic evolution and some language-specific features of the evolution of Judeo-Spanish, without an explicit appeal to exceptional solutions. Our hypothesis is based on the realization of the sequence /ˈue/ as a hiatus (<i>ĵu.e.ves</i>, <i>tu.er.to</i>, <i>su.e.ño</i>, <i>nu.e.ra</i>) which eventually developed an epenthetic consonant. This epenthesis was velar (<i>ĵugueves</i>, <i>tuguerto</i>), the latter case also involving further vowel insertion in agreement with the historical phonetics of Judeo-Spanish (<i>ĵugüeves</i>, <i>tugüerto</i>). Examples with labial fricatives or nasals preceding the diphthong have followed this evolution and then lost the pretonic vowel, giving way to a consonantal cluster in which the second consonant is partially assimilated to the first (<i>sueño</i> &gt; *<i>s(u)güeño</i> &gt; <i>sfueño</i> or <i>esfueño</i>; <i>nuera</i> &gt; <i>n(u)güera</i> &gt; *<i>enmuera</i> &gt; <i>elmuera</i>, <i>ermuera</i> &gt; <i>muera</i>).
