The paper demonstrates that dependency-based syntax is in a strong position to produce principled and economical accounts of the syntax of constructs. The difficulty that constituency-based syntax has in this regard is that very many constructs fail to qualify as constituents. The point is evident with the box diagrams and attribute value matrices (AVMs) that some construction grammars (CxGs) use to formalize constructions; these schemata often represent fragments rather than constituents. In dependency-based syntax in contrast, constructions are catenae, (...) whereby a catena is a chain of words linked together by dependencies. The catena is a novel but well-defined unit of syntax associated with dependency grammar (DG). The constructs of CxGs are more amenable to analyses in terms of the catenae of dependency-based syntax than to analyses in terms of the constituents of constituency-based syntax. (shrink)
