In Czech linguistics research, semi-subordinate clauses, which are typical for spoken Czech, are most often classified as a type of parenthesis, while in the research conducted abroad they are connected with the issue of evidentiality. In this article, they are delimited as sentences restricting the validity of the content of the main clause, in transition between determination and parenthesis. These clauses are among the means of text construction. Semi-subordinate clauses have three traits: non-integration into another clause as its clause element, the trait of commenting on another clause (the second level in complex sentence is created by these traits) and the presence of a subordinating connective. In the first stage of classification, clauses with conditional, limitation and purpose adverbial conjunctions are analysed. In the second stage, they are classified based on whether they comment on the whole main clause, or (rarely) only an element of it. In commenting on the whole main clauses, their attitude type, having a subjectifying character, and the stylization type of commenting are distinguished. In the attitude type, epistemic modality in particular is explained.
