Marchand (1969) examines possible cases of lexical category change and distinguishes between two different types: (a) syntactic transposition of a word which is a purely grammatical matter and represents a regular syntactic pattern, e.g. government (in the sense of governmental) as in government job, and (b) derivation when a word changes its word or lexical class, a fact which is evident in form and syntactic behaviour and is irreversible, e.g. polar (Adjective) from pole (Noun). However, there are two important questions: (a) whether we can trace a cline between these two cases, and (b) what happens with less canonical cases of derivation, such as conversion. The focus of our study will be on morphological and syntactic processes resulting in Noun to Adjective change, and their analysis from a constructionist perspective (Booij 2010, Traugott & Trousdale 2013). We examine these questions on the basis of the competition between the adjectival use of the Dutch noun luxe ‘luxury’ and the adjective luxueus ‘luxurious’. We assume that their distribution is regulated by inflection, and will check the validity of this hypothesis by corpus data drawn from NLCOW14AX (Schäfer & Bildhauer 2012) and the Corpus Hedendaags Nederlands.
