The study discusses the use of reflexive pronouns as markers of middle situation types and questions the traditional generalization that only light or weak reflexives (e. g., German sich, Spanish se) appear as such markers. Based on an analysis of approximately 2000 examples drawn from the British National Corpus, it explores if and to what extent the English heavy reflexive itself can be found in such contexts. Moreover, it provides a typology of the middle situation types in which the form itself occurs and analyzes the processes that give rise to the use of itself in such contexts. While some incipient grammaticalization processes can be found, the study argues that self-intensification as well as various lexicalization processes need to be considered, too. It also provides an extensive quantitative analysis of the contexts in which itself occurs. The study concludes that morphologically complex or heavy reflexives can occur as markers of middle situation types, contrary to widely accepted accounts. Moreover, it argues that the traditional grammaticalization account given for the occurrence of reflexive pronouns as markers of middle situation types is too simplistic and needs to be revised.
