The possibility of syntactic variation of idiomatic expressions is of particular interest in Generative Syntax. Even for rather sematically oriented approaches such as Nunberg/Sag/Wasow (1994) it is syntactic variation which is crucial for determining an expression’s degree of decomposability.
In CoDII we tried to provide corpus evidence for syntactic variation of expressions containing bound words. We stuck to constructions mentioned in the literature. In addition to given corpus examples there may be further possibilities of variation for a given expression.
