According to traditional grammar adjectives are either attributive or predicative. This distinction is also referred to by P. T. Geach. In Polish analytic philosophy attributive adjectives have been divided into two categories: determining and modifying (K. Twardowski, I. Dąmbska). The difficulties connected with the formal expression of the role of attributive adjectives in the framework of the classical predicate calculus are known (H. Reichenbach, D. Davidson). The paper proposes two logical constructions built upon elementary ontology which characterise attributive adjectives. Since they are nominal calculi, they are more natural than the predicate calculus and they avoid the above difficulties. The first construction makes it possible, for example, to see Johannes Scotus Eriugena’s logical schema in De Divisione Naturae in a new perspective. The second additionally includes relations, relative names, adverbs, and adjectives derived from adverbs.
