But what does it mean, that we can't explain (i.e. describe) these elements but only name them? That || This might mean, say, that the description of a complex, if this complex consisted || consists, in a limiting case, || (in a limiting case) of only one element || square, is simply the name of the coloured square. || This might mean, say, that when a complex consists, in a limiting case, of only one square, then its description is simply the name of the || that coloured square.
     We || One might say here – although this easily leads to all sorts of philosophical superstitions – that a sign “r”, or “b || b” etc., may sometimes be a word and sometimes a sentence. But whether it “ || ‘is a word or a sentence” || ’ depends on the situation in which it is uttered or written. If e.g. A has to describe for B complexes of coloured squares and if he uses here the word “r” alone || by itself, then we may say that the word is here a description – a sentence. But if he memorises, say, || e.g. he is memorising the words and their meanings || what they mean, or if he is teaching another || someone else the use of the words and utters them in connection with ostensive teaching || while giving || with the appropriate gesture, then we shall not say that they are sentences here. In this situation the word “r”, for instance, is not a description; you name || are naming an element with it, || : – but it would be strange to say on that account || that's why it would be strange to say here that the element can only be named. Naming and describing, in fact, are not on the same level: naming is a preparation for describing. When you have named something you || Naming || With || In naming something you || we have not || haven't || haven't yet made a move in the language game, – any more than you have || you've made a move in a chess game || chess by setting a piece || putting a piece on the board. We may say: with the naming of a thing || by giving a thing a name nothing has || nothing's yet been done. It hasn't even || yet a name, – except in the game. That || This is also what Frege meant by saying that a word has meaning only in its connection with || the context of a sentence.
