The ‘of’ word
This chapter explores from both synchronic and diachronic perspectives the categorial status of words like English of and equivalent items in other languages. It evaluates, and ultimately comes down in favour of, the arguments for continuing to treat such items as prepositions and heads of PP even when they have lost independent semantic content and serve instead a purely grammatical function. This analysis is contrasted both with the proposal to assign them to the functional category K(ase), as favoured within current nanosyntactic work, and with an account in which they retain prepositional status but as non-projecting members of that class. In broader theoretical terms, the chapter argues that one of the benefits of LFG’s parallel architecture is the consequential economy in its postulated inventory of functional categories.
