Abstract

In the article I present a new way to integrate occasional expressions into Frege's semantic. The principal thesis of the article is that it is possible to construct an interpretation that is fully Fregean and which is immune to the counterexamples put forward by Perry and Kaplan. According to this interpretation occasional expressions are functional expressions that name first-order functions specified on objects. Such functional expressions taken together with the objects constitute so-called hybrid proper names. I argue that Frege's requirement that functions possess a value for every argument is not well justified for name-forming functions. In the second part of the article I present a proposal for the structural analysis of occasional expressions and I offer a definition of their domains.
