Grammatical meaning and types of grammaticalization

The research paper focuses on the specific character of the gram matical features and some particular cases of grammaticalization in the contemporary Bulgarian language. The grammatical feature could be expressed by one morpheme; it could be a categorically new combination of grammatical features and a combination of morphemes expressing them; two or more semantic features from one common could be distinguished with a slight difference in the form; a grammatical feature with reduced functioning could be added to the system of features of a new grammatical category, etc.
