I really liked this article on words that are like icebergs. When you think about it you can peel off layer after layer, and it’s not even sure one word means the same to you as it does to me, in fact it probably doesn’t. I wrote about Sapir-Whorf here, who claimed that your language affects the way you think (I simplify the reasoning of course), and in some way I DO believe that language (together with cultural heritage of course) affects the way you think. That’s why it may be so extremely difficult to grasp everything that lies beneath the surface, just as with the iceberg.
