The Ciskodas subdialect - the remote Vilniškiai dialect in Latgalia (that is especially interesting) is described in this article. According to the pronunciation of the stressed vowel o of the common Lithuanian language the subdialect of Ciskodas belongs to the ‘žãdininkai’ group (they say žãdis „žodis“). Rules of Dzūkai dialect are not applied before the vowel ė that is continued as a diphthong in spite of its fronting, evidently after ti, di >ci, dzi: indíeti', c' and dz' are used before fronted ā and ż instead of the affricates c and dz", e.g.: dunda/ „dantys“. In the subdialect of Ciskodas these consonants are very rarely mutated (before fronted vowels c and dž' more often correspond to c' and dz'). In the Ciskodas subdialect the consonants l, r and s were hardened long ago, š, ž, c, č later. Confirmation of this is to be found in the consonantal variants existing until today.
