ENThe article focuses on case marking of the arguments of deverbal nouns (action and agent nouns) in Lithuanian, with particular attention paid to argument alternation. As nominalizations derived from verbs taking nominative, accusative and genitive have already been studied, I mainly analyse nominalizations from verbs taking dative, instrumental and locative NPs, as well as PPs. Action nouns in Lithuanian retain more verbal features than agent nouns. Though action nouns tend to retain their oblique arguments, the choice of the argument with action nouns can depend on productivity, word order, semantic role and the animacy of the argument, while the alternation with agent nouns can depend on the form of the NP/PP and on the frequency of the word.
