Atypical of Greater Polish dialects however, is the presence devoicing of word-final consonants before vowels and liquids.

ę also denasalizes word finally and becomes e or sometimes a, resulting in the fact that feminine nouns in the accusative and nominative sound the same.

Before a consonant or word-internally ę decomposed to y + n, ń, or m.[2] The cluster oN shows prenasal raising, giving óN.

[2] Adjectives, numerals, and pronouns frequently take -ę, which may be realized as a, instead of -ą for the feminine accusative singular, as in nominal declensions.

[2] The ending -ma is sometimes used for verbs in the first person plural imperative, common to Greater Polish: róbma (róbmy).

However, the first person plural past and sometimes present may also more frequently be formed with -m, common to northern lect generally: wyślim (wyszliśmy), przyjdziem (przyjdziemy).

[2] Due to Masovian influence, -ił/-ył shifts to -uł in the past tense of verbs: chodziuł (chodził).

[2] The feminine first person singular past tense is sometimes formed with -óm instead of -am, an innovation unique to the area; this is mostly found in folk songs: skakałóm (skakałam).

[2] The third person plural past tense often ends in -eli, or sometimes -oli where in Standard Polish it is -ali: śpieweli (śpiewali), loli (lali).

Nouns denoting young animals and people are often formed with -ak due to Masovian influence, rather than -ę.
