General location across languages: On the division of labour between functional and lexical items in spatial categories.

In many languages, it is possible to describe the location of any entity with respect to a landmark object without specifying the exact place that the locatum occupies (e.g. English at in at home). Such vocabulary items usually contrast with items that belong to the same categories but have more restricted senses (e.g. on top of in on top of the shelf). Thus, the degree of "abstractness" that such spatial case markers can convey usually depends on the organization of the lexicon and grammar of spatial terms in each language. The goal of this paper is to explore these properties across a small sample of languages and offer an account of this variation that is connected to previous theories of spatial case markers (e.g. adpositions). Our key proposal is that the morpho-syntactic structure of spatial case markers and their phrases can license a clear division of labour between functional and lexical spatial senses. However, intermediate solutions blurring categories and semantic boundaries are shown to be possible. We formalize this proposal via a fragment of Lexical Syntax, and show that degrees of distinction between 'functional' and 'lexical' sense types and categories can be modelled via a unified account.
