:: Sequences ::

The contiguous appearance of two vowels in a spoken chain produces hiatus or diphthongs, depending on its heterosyllabic or homosyllabic pronunciation. There has always been a tendency towards vowel reduction both in hiatus and diphthongs. Similarly, the secondary vowel sequences frequently appear through the loss of specific intervocalic consonants (basically [β, ð, ɣ, ɾ]).

The diphthongs resulting from the vowel phonemes are the following: [ei̯], [eu̯], [ai̯], [au̯], [oi̯], [ui̯], all of them decreasing. The absence of increasing diphthongs is a traditional feature of the language; instead, hiatus, consonantic epenthesis and reductions are produced. However, nowadays the presence of increasing diphthongs is always more frequent.

The occurrences of hiatus can be of a different kind: it can occur within a lexical element by derivation or composition, in verbal forms, etc.; in these realisations the hiatus or its results are generally fixed. Another kind of hiatus is produced by the adjunction of a morpheme to a lexical or verbal basis; in these cases the use of this morpheme is optional and therefore also the existence of the hiatus and its different diatopic realisations. In this last group certain sequences stand out, those that are produced by the juncture of the determiner [-a] with each of the vowels in final position of the word:[-ia], [-ea], [-aa], [-oa], [-ua] and also [-ya] for Souletin; these sequences registrate, as mentioned, a great variety of results, so that even cases of polymorphism exist, which is both social and individual in the same locality. Therefore, they have been included in this present work.
