This book contains a selection of papers on issues of current interest in syntax and morpho-syntax. Most topics pertain to the question of the relation between word order and syntactic structure. The discussion starts with a proposal of extending the theory of relativization to reason clauses. It continues with the analysis of the realization of focus in Basque and the discussion of current views on the syntax of cleft constructions. Next, an inquiry into the rigidity of sentence left-periphery is offered in a cross-linguistic perspective. The two final contributions discuss feature-free derivations in syntax applied to a single morpho-syntactic problem, and the question of gradient acceptability of Polish sentences featuring possessive items in the context of the competition between their reflexive and pronominal forms.
