The participants were asked to rate the appropriateness of pairs of imperative sentences differing in the aspectual form of the verb against the suggested discourse context. The analysis of the ratings revealed assumed deviations from the baseline in L2Ls. The HLs also revealed deviations, but unexpectedly, did not follow the baseline tendencies of the control monolingual group. Frequency and learning experience are some of the possible explanations of these finding and implications for pedagogy.en-USAll Rights Reserved.AspectHeritageImperativesPragmaticsRussianSLAElectronic Thesis or Dissertation
