In this thesis I investigate Donnellan’s Referential / Attributive distinction (R/A distinction); a distinction about using (say) definite descriptions in two truthconditionally different ways. I propose an argument from non-misdescriptions to the R/A distinction which does not utilise those cases of misdescriptions that Donnellan focused on. After arguing that the distinction should not be captured via conversational implicature, I point out a certain systematicity between the two relevant uses which tells against the view that the R/A distinction arises due to lexical ambiguity. I then extend the R/A distinction to demonstratives like ‘that F’ as well as some pronouns and suggest that it may be even more pervasive. Given this syst...
