ENThis paper gives an overview of the conducted research on Lithuanian multi-word expressions, particularly, collocations, and presents the developed resources. Beginning from the identification, analysis, and lexicographic description of MWEs in general, the focus of the research was narrowed down to collocations and their certain features, such as arbitrariness, during the later stages. Arbitrary collocations were seen as having lexically motivated relations and a certain degree of restricted collocability of constituents. Within the framework of the two projects, PASTOVU (2016-2018) and ARKA (2020-2022), corpus-driven approaches were applied to extract and document Lithuanian collocations and develop a number of lexical resources to be discussed in this paper. Keywords: Lithuanian multi-word expressions, Lithuanian collocations, arbitrary collocations, Gravity Counts, hybrid methods for collocation identification, lexical resources. [From the publication]
