ENThis article explores the topmost superlexical prefixes of the Baltic verb the Lithuanian te- and ne- and the Latvian jā- and ne- from the generative perspective. The prefixes are examined in light of the Split-CP framework. The proposed analysis formally accounts for the placement and interplay of the prefixes, in particular, the permissive and restrictive meanings of te-, the interaction between te- and ne- in Lithuanian; the debitive prefix jā- and its incompatibility with ne- in Latvian. The findings of this article contribute to the debate on the distinction of the debitive as a separate mood. [From the publication]
