 Actions in a dialogue are called moves; they are often understood as speech-acts involving declarative utterances (statements) and interrogative utterances (requests). The rules for dialogues thus never deal with expressions isolated from the act of uttering them; by defining the appropriate interactions in a dialogue, these rules define the meaning of the expressions. Such an approach to meaning finds its roots in Wittgenstein’s observation that in language, there is no exterior perspective that would allow one to determine the meaning of something and how it links to syntax. In other words, language is unavoidable, one cannot go beyond it (this is Wittgenstein’s “Unhintergehbarkeit der Sprache”). Accordingly, language is studied with and through language-games; these language-games need to acknowledge the fact that they are part of their object of study. In this respect, all the speech-acts pertaining to the meaning and “formation” of an expression are made explicit in the dialogical framework. We are thus far from the metalinguistic perspective constitutive of the model-theoretic conceptions of meaning (see Lorenz 1970: 109; Sundholm 1997; 2001).
