"I want to restrict the term 'name' to what cannot occur in the combination 'X exists'. -- And so one cannot say 'Red exists', because if there were no red, it could not be spoken of at all." -- More correctly: If "X exists" amounts to no more than "X" has a meaning -- then it is not a sentence which treats of X, but a sentence about our use of language, that is, about the use of the word "X".

- Wittgenstein, from Philosophical Investigations, from §58.


For a large class of cases of the employment of the word "meaning" -- though not for all -- this word can be explained in this way: the meaning of a word is its use in the language.

- from §43.
