FASL 27, ###-### Michigan Slavic Publications 2018 Frequency as a (Non)-Predictor of Acceptability: Russian V-N Collocations with Čto-Clause Complements * Mikhail Knyazev Higher School of Economics in Saint Petersburg, Saint Petersburg State University, Moscow State University of Education The aim of this paper is to evaluate the previously proposed hypothesis that čto-clause complements of nouns are restricted to V-N collocations with the restructuring property. The hypothesis was supported in an acceptability rating study, which found an interaction between restructuring and the clause type. The paper addresses a confound of that study arising from the frequency contrast between restructuring and non- restructuring V-Ns. The effect of frequency on the acceptability of čto- clauses was tested in a forced-choice experiment controlling for the effect of restructuring. The results did not provide clear evidence for the frequency effect, lending indirect support to the grammatical account. * The study is supported by the RSF (Russian Science Foundation) project 16-18- 02003 “Structure of meaning and its mapping into lexical and functional categories of Russian” at MSPU (Moscow State University of Education).
