Recent theoretical descriptions of the Icelandic case system distinguish between lexical and structural case. Lexical case is assigned in the lexicon, whereas structural case is assigned in syntax, under the provision that it does not override lexical case assignment. This analysis is problematic for grammatical theories such as Categorial Unification Grammar (CUG) and Head driven Phrase Structure Grammar (HPSG) as the introduction of a syntactic case component is incompatible with the lexicalist ideology underlying these frameworks. Furthermore, the default character of syntactic case introduces a procedural aspect into the grammar which goes against the declarative spirit of unification-based frameworks in general. In this paper, I propose an alternative analysis, formulated in terms of CUG, in which all case constraints are expressed lexically and in which default reasoning is restricted to nonmonotonic inheritance of lexical information only.
