§16. What about the colour samples that A shews to B: are they part of the language? Well, it is as you please. They do not belong among the words; yet when I say to someone: "Pronounce the word 'the'", you will count the second "the" as part of the sentence. Yet it has a role just like that of a colour-sample in language-game (8); that is, it is a sample of what the other is meant to say.
It is most natural, and causes least confusion, to reckon the samples among the instruments of the language.
((Remark on the reflexive pronoun "this sentence".))
