A language-game (German: Sprachspiel) is a philosophical concept developed by Ludwig Wittgenstein and Friedrich Waismann, referring to simple examples of language use and the actions into which the language is woven.
In his work, Philosophical Investigations, Ludwig Wittgenstein regularly referred to the concept of language-games. Wittgenstein rejected the idea that language is somehow separate and corresponding to reality, and he argued that concepts do not need to be clearly defined to be meaningful. Wittgenstein used the term "language-game" to designate forms of language simpler than the entirety of a language itself, "consisting of language and the actions into which it is woven" (PI 7) and connected by family resemblance (Familienähnlichkeit). The concept was intended "to bring into prominence the fact that the speaking of language is part of an activity, or a form of life, " (PI 23) which gives language its meaning.
The term 'language-game' is used to refer to:
These meanings are not separated from each other by sharp boundaries, but blend into one another (as suggested by the idea of family resemblance). The concept is based on the following analogy: The rules of language are analogous to the rules of games; thus saying something in a language is analogous to making a move in a game. The analogy between a language and a game demonstrates that words have meaning depending on the uses made of them in the various and multiform activities of human life. (The concept is not meant to suggest that there is anything trivial about language, or that language is "just a game.")
The classic example of a language-game is the so-called "builder's language" introduced in §2 of the Philosophical Investigations:
The language is meant to serve for communication between a builder A and an assistant B. A is building with building-stones: there are blocks, pillars, slabs and beams. B has to pass the stones, in the order in which A needs them. For this purpose they use a language consisting of the words "block", "pillar" "slab", "beam". A calls them out; — B brings the stone which he has learnt to bring at such-and-such a call. Conceive this as a complete primitive language. (PI 2.)
