The author states that there are in our vocabulary three, and only three, classes of semantic units: a) predicates, i.e. generic concepts – the result of our conceptualization of the world; they represent more than 90% of the vocabulary; b) operators of reference – a small, almost closed set bounding predicates to their concrete denotates; c) proper names, which are by defi nition referentially bound and are object of research of a specialized linguistic discipline. Thus, the main tasks of our grammar are (1) to defi ne and to describe the scope of the grammaticalization in the language in question and (2) to present the semantic classification of predicates, the description of their – bound and/or free – functioning in the text included.
