This article presents a multivariate analysis of adversative conjunction choice (among no, da, and odnako) in Russian, drawing implications for sentence production and semantic theory. The two main factors shown to influence conjunction choice are the types of the conjoined constituents and the semantic subtype of the adversative relation. One of the conjunctions, da, is favored when the conjoined elements are of different syntactic types and disfavored when they are of the same type, which is argued to suggest that the conjunction is chosen at a point in sentence production when the types of both of the conjoined constituents are known (Uryson, 2006). In addition, the conjunction da is heavily favored by the “preventive” adversative meaning (Sannikov, 1989:177; Serebrjanaja, 1976), as in I would go but I don't have the money. This quantitative meaning-construction association is argued to support the view that the preventive adversative is a distinct semantic subtype of adversativity (Payne, 1985; contra Foolen, 1991:84).
