This study investigates the linguistic realization of information structure (IS) in Turkish. Following Vallduvi and Engdahl [Linguistics 34 (1996) 459], Hoffman (Hoffman, B., 1995. The Computational Analysis of the Syntax and Interpretation of "Free" Word Order in Turkish. Unpublished PhD dissertation, University of Pennsylvania), and Kilicaslan (Kilicaslan, Y., 1994. Information Packaging in Turkish. Unpublished MSc dissertation, University of Edinburgh), it is assumed that IS has a tripartite structure, consisting of topic, fail, and focus. The main claim of this paper is that syntax and phonology, by means of word order and prosody, are both responsible for the realization of the IS units. Thus, neither syntax nor phonology can be reduced to a secondary role. The word order-prosody interface reveals that presentational-focus and contrastive-focus are two distinct phenomena in Turkish, which are marked by different focusing strategies, i.e. syntactic and prosodic. It is shown that without drawing the distinction between the two types of focus, focusing phenomena in Turkish cannot be explained. This study also provides a schema representing the surface level structuring of IS in Turkish. At the same time, it is brought to light that in the interaction between specificity and IS, word order is employed in an extremely 'free' way to mark the ground elements. This empirical fact suggests that the relation between specificity and IS is far more complex in Turkish than suggested in the previous literature. (C) 2003 Elsevier Science Ltd.
