Phonological and morphological characteristics

Vowel change я/broad е (ʲa/æ) instead of formal Bulgarian я/е (ʲa/ɛ) for Old Church Slavonic ѣ – (бял/бæли instead of бял/бели). As a result of the influence of the
Balkan dialects
, the broad e (æ) has now been almost universally replaced by (ɛ)
щ/жд (ʃt/ʒd) for Proto-Slavic *tʲ/*dʲ (as in Standard Bulgarian) - нощ, между (night, between)
Universal loss of x /x/ and ф /f/. The two consonants are either completely lost or replaced by v or w
The masculine definite article is о (stressed) and у (unstressed) instead of formal Bulgarian –ът/ъ (гърˈбо, ˈстолу instead of гърˈбът, ˈстолът). As a result of the influence of the
Balkan dialects
, the о/у definite article has largely been replaced by –ът/ъ
ending e instead of formal Bulgarian i for multi-syllable masculine nouns (българе instead of българи)
ending e instead of formal Bulgarian i for plural past active aorist participles (биле instead of били)
Preposition у instead of formal Bulgarian в (у Русе instead of в Русе)
