Quasi-proper names, language use and contextualism

In this paper, I discuss expressions such as ‘Dad’, ‘Mum’, ‘Grandpa’, etc., which are called ‘quasi-proper names’. These expressions can be used both to refer to a thing or person in an assertion in which a predicate is assigned to the referent expressed by the quasi-proper-name and to call somebody in particular (John!). In so far as they are indexical expressions, they are even more directly referential than proper names and guarantee discourse continuity to a greater extent than proper names (even if this appears to some to be controversial). To understand the working of quasi-proper names, I introduce a semantic rule that transforms nouns or definite descriptions into proper names and quasi-proper names, making the conceptual elements present in those expressions inactive and introducing a direct route from the proper name to the referent. Such a rule is synchronic, although it has diachronic consequences. Quasi-proper names can stimulate a debate about the function and role of proper names across cultures. I consider a number of expressions similar to quasi-proper names and I add the class of quasi-quasi-proper names (cases in which a term similar to a quasi-proper name can be used in vocatives but not in a subject-predicate structure, or, vice-versa, it can be used in a subject-predicate structure but not for vocatives).
