Features, Categories, and the Syntax of A-Positions investigates various aspects of the distribution of nominal arguments, and in particular the cross-linguistic variation that can be found among the Germanic languages in this domain of the syntax. The empirical topics that are discussed include variable vs. fixed argument order, the distribution of subjects with respect to adjuncts, expletive constructions, and oblique subjecthood.
