Abstract
This article gives a unified semantic analysis of the various uses of the Dutch discourse marker eigenlijk. Eigenlijk is analyzed as involving implicit assumptions of the speaker about the hearer's expectations: by using eigenlijk, the speaker marks the plausibility of what s/he assumes the hearer to infer on the basis of their shared beliefs. Hence, the speaker not only recognizes the discrepancy between the speaker's and the hearer's perspective, but in addition, the speaker puts him/herself in the hearer's shoes. The claims are empirically supported by the results of a web experiment as well as by data from natural language.
