Phonological and morphological characteristics
- Vowel a for Old Church Slavonic ѫ (yus), ь and ъ: маж vs. formal Bulgarian мъж (man), сан vs. formal Bulgarian сън (sleep)
- щ/жд (ʃt~ʒd) for Proto-Slavic *tʲ~*dʲ (as in Standard Bulgarian) - леща, между (lentils, between). The future tense particle, however, is ше, к҄е, к҄у

- Verb ending -a instead of formal Bulgarian -ъ in verbs of the first and second conjugation: чет'а vs. formal Bulgarian чет'ъ (I read)
