In reading Wittgenstein one can, and for the most part perhaps should, treat the expression ‘language-game’ as a term of art, a more or less arbitrarily chosen item of terminology meaning something like ‘an actual or possible way of using words’. It would then be a fairly routine task to work out answers to such questions as what features of the ways a word is used are emphasized by this term of art, what philosophical purposes are served by the description of primitive language-games or of variations on actual language-games, or in exactly what way those purposes are supposed to be served.
