The paper presents a brief overview of the history of the corpus approach in Slovenian language studies & the existing corpora of the Slovenian language. These corpora have provided an incentive for a series of thorough linguistic studies, both monolingual & contrastive; at the same time they are becoming an indispensable part of general linguistic research, especially in the field of lexical or lexicosemantic studies. In the second part of the paper, a case study illustrates one of the procedures in lexical corpus analysis: using selected examples, we demonstrate how it is possible to track changes in the lexis of the Slovenian language in the last decade of the twentieth century.
