Language is the most revelational aspect of the inner thoughts and attitudes of man. It is in his language that man reveals his inner life. His subconscious overflows and, before he is aware of it, he has already exposed his inner self.
Languages are constantly in flux.
Whole societies could be identified by studying their changing attitudes when considering the use of their words and expressions, including the words which have fallen into disuse and those which have replaced them. Hebrew is a most powerful example of this phenomenon. A comparison of how the biblical and Talmudic mind used Hebrew and how in our days the language has deteriorated is most telling. In fact, languages that express possession in this way, rather than by 'I have' predominate. This does not mean that there is no such concept as possession in Hebrew.
