This is not for skwim, it is beyond his comprehension skills. But to sum up my points.
How words connect to reality is a mystery.
Why? Bexause words have nothing in common with concepts and concepts have nothing in common with reality. Suppose I try to explain what an elephant is by handing you an apple. Since they have nothing in common, I have not explained to you what an elephant is. Imagine a map. How does it inform us of the landscape ? Because it has something in common with the landscape. The shape of the lines on the map are similar to the shape of the land.
However ,lets provisionally (temporarily assume that the absurd idea that conxepts resemble reality is true) take the common sense theory how concepts attach to reality. Wittgenstein used the colored balls in a bag thought experiment to show that even then, we have no explanation as to how concepts attach to reality. I have a bag full of colored balls. Red, blue, green etc. I tell you to pick out a red one. The common sense theory about how this is possible is that you hear the word "red"
