Last year, Katharina Turgay and I gave a talk on the acquisition of functional categories in German prepositional phrases at Generative Grammatik des NordenS (GGS)in Berlin. An article that is based on that talk but elaborates on it in many respects has now been accepted for publication in the Zeitschrift für Sprachwissenschaft. In the paper, we describe and evaluate a study with 40 Turkish speaking primary school children in L2 acquisition (together with two control groups of children in L1 acquisition) in order to examine how the functional categories D, Path and Place are acquired. A manuscript version of the paper can be found here.
