Petersburgian

Petersburgian is a descendant of the Modern Russian language, spoken in Saint Petersburg and most surrounding areas.

Classification and Dialects
Petersburgian evolved from a local accent of Russian. It has been influenced by neighbouring languages, including North Russian dialects, Estonian and Finnish. It is closely related and partly mutually intelligible with other descendants of Russian, including "Standard Russian" (the language spoken in Moscow).

Consonants
/tʃ/ and /dʒ/ have merged with /tɕ/ and /dʑ/ respectively for some speakers. /x/ is often realized as [h].

Vowels
The vowel system has undergone various changes, most of those being the effect of the stress shifts onto the first syllable. Unlike Russian, where there are six vowels with multiple stress-related allophones, Petersburgian has an extensive vowel system with ten vowels and three diphthongs.

/ɨ/ is sometimes analyzed as /ɤj/ due to absence of minimal pairs.

Writing System
Petersburgian uses its variant of the Cyrillic alphabet.

Verbs
In the non-past tense, verbs inflect for person and number, while in the past tense they inflect for gender and number.

Nouns
Nouns in Petersburgian decline for gender, number and case. Many nouns undergo ablaut and apohony in the plural forms and sometimes even when changing cases. Nouns also take possession marking.

Pronouns
Pronouns in Petersburgian decline more than nouns do. They also have different cases not present in nouns, like the adessive case, used to create possessive constructions.
