§83

Language could perhaps illuminatingly be compared to people going out and having fun with a ball. They might start playing an existing game but not complete it and then throw the ball aimlessly into the air. They might throw the ball at one another for a joke, and so on. They are not following definite rules at every throw - just as people uttering words/sentences are not following definite rules with every utterance. The analogy between language games and games is illuminating but we should not think that language always involves following definite rules.
