Categoriality in Language Change
This study presents the first elaborate attempt to set out a functional-semantic definition of diachronic transcategorial shift between the major classes “noun”/“nominal” and “verb”/“clause.” In English, speakers have different options to refer to an event by using “deverbal nominalization” strategies (e.g., Him guessing her size/His guessing of her size (was incredibly lucky)). Interestingly, not only do these strategies each resemble “prototypical” nominals to varying extents, it also has been observed that some of these strategies increasingly resemble clauses and decreasingly resemble prototypical nominals over time, as if they are gradually shifting categories. Thus far, the literature on such cases of diachronic categorial shift has mainly described the processes by focusing on form, leaving the reader with a clear picture of what and how changes have occurred. Yet, the question of why these formal changes have occurred is still shrouded in mystery. This study tackles this mystery by showing that the diachronic processes of nominalization and verbalization can also involve functional-semantic changes. The aim of this study is both theoretical and descriptive. The theoretical aim is to present a model that allows one to study diachronic nominalization and verbalization as not just formal or morpho-syntactic but also functional-semantic processes. The descriptive aim is to offer “workable” definitions of the abstract functional-semantic properties of nominals and verbs/clauses, and subsequently apply them to one of the most intriguing deverbal nominalization systems in the history of English: the English gerund.
