The relation between the verb držati (se) and its grammatical derivatives in the light of aspectual correlation

In contemporary aspectological researches, especially in those within the domain of category aspect verb lexemes formalized as a binary category, there are more and researches oriented to empirical verification claims about its non nature. This paper also has such orientation, precisely on example držati, reflexive form držati se, grammatical derivatives (e.g. udržati, sadrža(va)ti, podržati, pridržavati (se), pridržati prodržati etc.; registered consulted dictionaries), we try show that verbs is complex system than one, i.e. numerous typological structures by which verbal aspect, inherent each verb, can be formalized.
