The study deals with the collocations 'SUBST + AKO + INF' and their syntactic status determining the writing of comma in the selected types of constructions. Reviewing the items of the Slovak National Corpus, the most frequent nouns realized within this type of constructions are identified. The corpus research proves that the attributive monomial infinitive sentences undergo complex sentence constructions, which can result into the syntagma with a simple attribute within the particular group of nouns. This process is reflected in the irregular comma writing realized within the corpus texts.
