an argument structure construction that expresses the relationship between the participant roles of an event expressed in a clause and their relative salience (topicality). Examples: The grizzlies ate the salmon and The salmon were eaten by the grizzlies are instances of contrasting voice constructions, the basic voice construction and the nonbasic voice construction (specifically, the passive–inverse construction), which are appropriate in different discourse contexts, depending on whether the grizzlies or the salmon is the more salient participant at that point in the discourse.
