 Inspired by Ludwig Wittgenstein’s idea of a language-game, Hintikka (1968) introduced the basic framework of what came to be known as game-theoretical semantics (a.k.a. GTS). The basic lesson Hintikka adopts from Wittgenstein is that words – in particular quantifiers – are associated with activities that render them meaningful: words often have meaning only in the context of certain types of action (Hintikka 1968: 55–56). Wittgenstein said that by ‘language-game’ he means ‘the whole, consisting of language and the actions into which it is woven’ (Wittgenstein 1953: I, Sect. 7).
