The article deals with one type of subordinate clauses expressing causality, namely pronominal-particle clauses in the present Czech. The incorporation of these clauses into the head clause lies in the fact that they express broadly understood causal meanings of adverbial subordinate clauses using primary and secondary prepositions and multiple-word units together with the pronoun to, which anticipates the subordinate clause introduced by the connecting particles že, aby. Data from the Czech National Corpus concerning subordinate clauses of cause (reason), purpose, condition and concession are analysed from the point of view of the Czech language (grammar) system.
The article offers a semantic classification of pronominal-adverb clauses expressing broad manner. The pronoun ten incorporated into the head clause most often by a secondary preposition or as a part of a multiverbation unit anticipates a subordinate clause of broad manner introduced by a pronominal relative adverb. The centre of broad-manner clauses is formed by clauses expressing narrow manner, extent or degree, means, accompanying circumstances. Clauses expressing exception and respect are close to the periphery. The periphery is formed by clauses expressing appropriate action and clauses with a relationship of attachment.
