The aim of this thesis is to examine the morphosyntactic and semantic properties of abstract nouns related to verbal and adjectival predicates. Since the nouns we examine are linked to verbal and adjectival predicates, the first part focuses on the question of aspectual properties in the nominal domain. We show that 'intensive abstract nouns' (Van de Velde 1995 and Flaux & Van de Velde 2000) constitute a unified aspectual class characterized by the feature [-DYNAMIC]. From the assumption that the stative feature common to these nouns allows a unified analysis, we propose a study relying on the idea that stative nouns are distinguished by their uses, and show that, in addition to a purely stative meaning, these nouns can also convey other information, in which they denote occurrences. The second part is dedicated to the syntactic behaviour of stative nouns, i.e. number and determination, but also adjectival modification. This enables us to identify two distinct morphosyntactic behaviours, that parallel the distinction between stative and occurrence understanding highlighted in the first part. On the one hand, in their property sense, these nouns have a behaviour similar to that of massive concrete nouns and qualify as relational nouns, i.e. they require an argument with which they enter into a predication relationship (at the syntactic level). On the other hand, in their occurrence sense, these nouns behave like concrete count nouns and are not inherently relational. To sum up, the analysis of stative nouns shows that they share semantic properties with certain types of verbal and adjectival predicates, as well as syntactic properties with various classes of concrete nouns.
