Probing Aspectual Context with Keyword Analysis* Václav Cvrc ˇek and Masako Fidler Abstract: Tis paper explores the contextual paterns that are most relevant to Czech verbal aspect by means of a corpus linguistic method of keyword analysis. In addition to the ex- pected relevance of temporal-aspectual constraints, the study shows two other factors that are less frequently addressed quantitatively: lexical-phraseological atraction and genre/ text type. Janda’s idealized cognitive model of “mater” (2004) will be used to account for the obtained results. 1. Introduction: Extending the Notion of Context Verbal aspect, one of the most extensively studied areas of Slavic linguistics, has normally been discussed in relation to context—to the contents of a clause or a sen- tence and beyond the sentence. Forsyth’s structuralist markedness model of verbal aspect (1970) implicitly includes context: components within and beyond a sentence such as adverbs, adverbial phrases, and situations. Bermel and Kořánová (2008) ar - gue that adverbs and adverbial phrases (“temporal-aspectual markers”) are central to teaching Czech verbal aspect. In Timberlake’s (1982) model aspectual choice in Russian is determined by “closure” of events on the propositional level; the later is identifed by a point of reference (“aspect locus”) implicitly or explicitly referred to in context. Dickey and Kresin (2009) observe the textual functions of grounding and aspectual choice in Czech and Russian. Te goal of this paper is to explore the range of context that is most relevant to Czech aspectual selection by means of a corpus linguistic method of keyword analysis. Tis method shows the relevance of temporal-aspectual constraints and of two other factors that are less frequently addressed quantitatively: lexical- * Tis study was writen within the Programme for the Development of Fields of Study at Charles University, No. P11 Czech national corpus.
