The article focuses on the links and relationships between morphological and syntactic categories in Slovak as a flectional type of language, emphasising the essence of the syntactic categories and their classification. The relationships between morphological and syntactic categories are based on the fact that the morphological units serve the construction of syntactic units. According to the author, syntactic category is a meaningful and formal unit which serves the study of fundamental aspects of the grammatical and semantic sentence structure, as well as its communication function. In this connection three main syntactic categories (or hyper-categories) are distinguished: the predicative category, the category of modality and the category of communication intention. To these three hyper-categories can be attached other categories or subcategories which express more specific aspects of the grammatical and semantic sentence structure (personality, appeal, the category of syntactic correlativity, negation, etc.).
