Petersburgian

Petersburgian is a descendant of the Modern Russian language, spoken in Saint Petersburg.

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

 * Most consonants can be geminated, except for /w/, /h/ and /j/. Some consonants, like /ɖʐ/, only occur as geminates in loanwords. Word-initial geminates are allowed as well.

Vowels

 * All vowels can form a diphthong with the oral or nasal version of either /j/ or /w/ as the second component.
 * [o] is rare outside of the combination [wo].
 * /ɨ/ can only occur after a consonant.

Phonotactics
Petersburgian allows multiple consonant clusters, however most of them are simplified compared to those in Modern Russian. A syllable can have a structure of (C)(C)(G)V(V)(C)(C) (with G being a glide).

Writing System
Petersburgian uses its variant of the Cyrillic alphabet.

Nouns
Nouns are moderately inflected. They inflect for number, case and gender. Definite articles have formed under the influence of the definiteness markers in Northern Russian dialects. The neuter gender has mostly been lost and/or merged with the feminine, and only relics and vestiges remain.

Adjectives
Adjectives, just like nouns, inflect for case, number and gender.

Verbs
Verbs are inflected for aspect, tense, mood, person and number (in non-past tenses) and gender (in past tenses).

As in Russian, verbs are put in the perfective aspect by adding a prefix, such as pro-, po-, h-, so-, rah-.

Petersburgian has preserved many Russian pairs of verbs of motion, such as plavacĭ/plycĭ (to swim), ljetacĭ/ljetjecĭ (to fly), vodicĭ/vetti (to lead), itti/hodicĭ (to walk, to go). Those verbs indicate multidirectional and unidirectional movement, respectively.

Syntax
As in Russian, word order is relatively free but the default order is SVO, with adjectives and possessives before the noun.
