Participles, gerunds and syntactic categories

The phenomenon of so-called ‘mixed’ categories, whereby a word heads a phrase which appears to display some features of one lexical category, and some features of another, raises questions regarding the criteria used for distinguishing syntactic categories. In this paper I critically assess some recent work in LFG which provides ‘mixed category’ analyses. I show that three types of evidence are typically utilized in analyses of supposed mixed category phenomena, and I argue that two of these are not, in fact, crucial for determining category status. I show that two distinct phenomena have become conflated under the ‘mixed category’ heading, and argue that the term ‘mixed category’ should be reserved for only one of these.
