Abstract

This study seeks to explain choices in everyday language use in corpus data. It examines the variation between if and whether as complementisers in interrogative subordinate clauses. In closed interrogative clauses, both if and whether are used as complementisers, e.g., I’m not sure if / whether that happened. This variation has so far received only little attention in the linguistic literature. This study draws on data from the International Corpus of English (ICE) to provide more insight into the use of these alternatives. Based on data from ICE-Great Britain, ICE-Ireland and ICE-New Zealand, I examine the distribution of both complementisers in different text types and in regionally diverse varieties of English. Different statistical analyses (logistic regression, conditional inferences trees, random forest) are used to identify the most important predictors of the complementisers, with a focus on cognitive linguistic features. The analysis reveals that the strongest overall predictor of the variation between if and whether is the matrix verb controlling the interrogative clause. By combining register, regional variety and cognitive factors as predictors of the choice between if and whether, this study sheds light on the interplay of external and internal factors in making linguistic choices, and on the importance of cognitive factors in complementiser choice in general. Thus, it adds to our insight into the production of linguistic output that draws on real-life experience.
