This study tests the morphological gradience theory on Russian prefixed verbs. With the help of a specially designed experiment, in which participants were asked to evaluate the semantic transparency of a prefixed nonse verb given in minimal context, as well as to semanticise it by suggesting an existing Russian verb with the same prefix, we offer evidence that these verbs can be analysed as constructional schemas and that the degree of their morphological decomposition depends upon the different levels of activation of their sequential and lexical links. We prove that speakers of Russian are very sensitive to the etymological connection between verb prefixes and the prepositions they are related to. Thus, prefix-stem constructions with prefixes that correspond to prepositions are more likely to be morphologically decomposed, while prefix-stem constructions with prefixes that do not relate to prepositions tend to be regarded as single lexical units. Moreover, the general, highly abstract semantics of Russian prefix-stem constructions, especially of those that retain their ‘prepositional’ meaning, is undoubtedly accessible to language users, which is confirmed by the fact that the interpretability of these constructions is affected by priming.

这项研究测试了俄语前缀动词的形态学梯度理论。在一个经过特殊设计的实验的帮助下，参与者被要求评估在最小上下文中给出的带前缀的鼻子动词的语义透明性，并通过建议一个具有相同前缀的俄语动词来对其语义化，我们提供了证据这些动词可以作为结构图式进行分析，其形态分解的程度取决于其顺序和词汇联系的激活水平。我们证明俄语使用者对动词前缀和与其相关的介词之间的词源联系非常敏感。因此，具有与介词相对应的前缀的前缀词干结构更有可能在形态上分解，而具有与介词无关的前缀的前缀词干结构往往被视为单个词汇单元。此外，俄语用户使用词干结构，尤其是保留其“介词”含义的词组，通常具有高度抽象的语义，对于语言用户而言无疑是可以访问的，这一事实证实了这些结构的可解释性受到启动的影响。
