The article is devoted to chosen titles and subtitles in Slovene-language popular science texts about Slovene history. The data comprise 110 examples taken from the three Slovene popular science books. The analysed phrases have different forms (nouns, adjective-modified nouns, nominalizations). The conducted study is methodologically based on semantic and syntax analysis – the analysis of the ways of realization of the predicate-argument structure on which a given initial para-text is founded – as applied in the context of textual analysis of scientific, and especially popular scientific, discourse. The author of the article investigates the relation between the given title and the content of the corresponding portion of the macro-text. Particularly interesting are titles formed by means of nominalization, that is to say – by means of a transformation of predicate-argument structure. When used as titles, nominalizations confirm their expected semantic and syntax features, such as the capacity for the omission of chosen elements, increased generality and the same time compactness of the message. They also proved fruitful elements of the strategies of macro-text construction based on using appropriate titles.
