Abstract Pronominal constructions such as something big, often referred to as the ‘indefinite pronoun construction’, have received different but often homogenous accounts in the literature. In this paper, I document the inner- and cross-linguistic diversity of this construction in German and some other languages. Highlighting respectively different sets of properties, I argue that there are three basic types: one type combines the adjective and the pronoun by complementation, another by adjunction, and a third involves a garden-variety DP. Adjunction is argued to be mediated by a Modifier Phrase (Rubin, E.J., Proceedings of the West Coast Conference on Formal Linguistics, CSLI, Stanford, 429–439, 1996). The latter assumption is shown to have a number of advantages.
