Language is subjective. That is the sounds emanating from my mouth to your ears have zero intrinsic meaning except for how I understand them and how you understand them. There is nothing that is independent of the speaker and the listener.
Reality on the other hand is objective. For example the ocean is blue. That fact has nothing to do with how anyone observes the ocean. It is just the fact that it absorbs all frequencies of light except blue.
So language tells you nothing about reality.

So when Wittgenstein said after reading his Tractatus no one could be the same he was quite right. People began to think that language defines reality. They fell into that trap.
