Ding an sich of the meaning

I think that the ding an sich of the meaning is the essence of it, what makes it unique. also is when you related to what we understand of that meaning with what we can relate it. But for this is necessary to know what is a meaning: is a group of characteristics and concepts that made of a word o thing unique and different for the others. for example we difference a glass from a chair for their meaning and for the use, you know this because you inmediatly relate in our mind an image, the concept, the concept and the meaning build with experinces and with the time they are better.
The ding an sich of meaning is something special, that all the things have and is the essence. ( the meaning of meaning, when you relate the words that you see or listen what the things that you know).
