Siberian dialects are a group of Northern Russian dialects under the serious lexical influence of the Southern Russian dialects and foreign inclusions (primarily Turkic^[1] and sometimes Yukaghir and Even).^[2][3] It is spoken by Siberian old-timers: Siberiaks, Chaldons, Kerzhaks, Cossacks, Old Believers, Pokhodchans (Kolymchans), Russian Ustians (Indigirshchiks), and Markovites (Anadyrshchiks).

From a phonetic and grammatical point of view, Siberian dialects genetically go back to Northern Russian dialects and are characterized by okanye, clear pronunciation of vowels, plosive /g/, absence of /ɕː/ (replaced by long /ʂː/), dropping out vowels (which leads to changes in the adjective declension) and consonants, a variety of pluperfect forms,^[4][5] as well as frequent use of postpositive articles.^{[6][verification needed][7]}

Phonology

• /g/ and /k/ alternation;
• /f/ inclusion (еслиф, ислиф);
• Long /ʂː/ and /ʐː/ (шшука, дожжык);
• Differentation between /t͡s/ and /t͡ʃ/;
• The /st/ and /sʲtʲ/ endings are simplified to /s/ and /sʲ/;
• Vowel contraction (красна девка айдат).

Morphology

• Feminine genitive ends with -ы;
• Feminine dative and propositional ends with -е (в грязе);
• Masculine propositional has the same ending as instrumental (в баским доме);
• The чо interrogative pronoun;
• 3rd person verbal ending with non-palatalized -t as in Standard Russian;
• 1st and 2nd verbal conjugation endings are not differentiated in 3rd person plural. Both conjugations utilize –ут/–ют.
