At the time when we may suppose that the first attempts at finding a name for God were made, the divergence of the languages of mankind had commenced. We cannot dwell here on the causes which led to the multiplicity of human speech; but whether we look on the confusion of tongues as a natural or supernatural event, it was an event which the science of language has proved to have been inevitable. The ancestors of the Semitic and the Aryan nations had long become unintelligible to each other in their conversations on the most ordinary topics, when they each in their own way began to look for a proper name for God. Now one of the most striking differences between the Aryan and the Semitic forms of speech was this:--In the Semitic languages the roots expressive of the predicates which were to serve as the proper names of any subjects, remained so distinct within the body of a word, that those who used the word were unable to forget its predicative meaning, and retained in most cases a distinct consciousness of its appellative power. In the Aryan languages, on the contrary, the significative element, or the root of a word, was apt to become so completely absorbed by the derivative elements, whether prefixes or suffixes, that most substantives ceased almost immediately to be appellative, and were changed into mere names or proper names. What we mean can best be illustrated by the fact that the dictionaries of Semitic languages are mostly arranged according to their roots. When we wish to find the meaning of a word in Hebrew or Arabic we first look for its root, whether triliteral or biliteral, and then look in the dictionary for that root and its derivatives. In the Aryan languages, on the contrary, such an arrangement would be extremely inconvenient. In many words it is impossible to detect the radical element. In others, after the root is discovered, we find that it has not given birth to any other derivatives which would throw their converging rays of light on its radical meaning. In other cases, again, such seems to have been the boldness of the original name-giver that we can hardly enter into the idiosyncrasy which assigned such a name to such an object.
