Łęczyca and Sieradz have even been considered as one group due to the large number of similarities.
A feature tying Sieradz with Lesser Polish is the shift of final -ch > -k. Soft labials can weaken.
[3] Typically contraction occurs here, but rare uncontracted forms can are attested: stojały (stały).
Somewhat more common here than in Standard Polish is the use of the partitive genitive: zapolyli papiyrosów (zapalili papierosów).
[3] The feminine genitive/locative singular of adjectives, pronouns, and numerals and the comparative of adverbs may e -ij/-yj or less commonly -i/-y due to sound changes.
Archaically the past tense in the first person plural can be formed with jeśmy or -m or -my alongside -śmy (sometimes pronounced -źmy).
[3] Common is the extension of the prepositions w, z with mobile e to we, ze when before a word starting with a consonant of the same place of articulation.
Nouns denoting young animals and people are formed with -ak, as in Masovian dialects.
