Comparing explanatory principles of complement selection statistically : a case study based on Canadian English

Several factors have been identified in the recent literature to explain variation in the selection of sentential complements in recent English, and the article begins with a survey of such factors. The article then offers a case study of the impact of such factors on non-finite complements of the adjective afraid on the basis of the Strathy Corpus of Canadian English. Attention is paid for instance to the Extraction and Choice Principles, passive lower predicates, and text type. Multivariate analysis is applied to compare and to shed light on such different explanatory principles. The Choice Principle proves to be by far the most significant predictor of the alternation, while the heavily correlated syntactic feature of Voice appears non-significant. Fiction, as opposed to the informative registers, shows a notable preference for to infinitives, though this finding needs to be replicated in datasets where controlling for author idiolect is possible. Theoretically plausible odds ratios are observed on the Extraction Principle and negation of the predicate, but they are not statistically significant. In the former case, this may well be due to the variable’s collinearity with the Choice Principle and its low overall frequency, resulting in a low effective sample size.Peer reviewe
