The Diseases of Language 421 Nearly three thousand years ago, when Aryan-speaking mbes were letterless savages, Semitic trading peoples hit on the device embodied in our own alphabet Fully a thousand years before the true relation- ship between the principal European languages and Indo-Iranian was recognized, Jewish scholars, who applied the methods of then: Muslim teachers, had already perceived the unity of the Semitic dialects then known The Rabbi's interest in language problems was half-super- stitious, half-practical, like that of the Brahmamc priest or the student of the Koran His aim was to perpetuate the correct form, spelling, and pronunciation of the Sacred Texts; but there was a difference between the Brahmin and the Jew. Because he often lived in centres of Muslim learning such as Damascus, Seville, and Cordova, and also because he had mastered more than one tongue, the Rabbi could easily transgress the confines of his own language Inescapably he was impressed by similarities between Aramaic, Hebrew, and Arabic, and compelled to assume their kinship Though he used the discovery to bolster his belief that Hebrew was the parent of Arabic, and incidentally of all other languages, he planted the seed of comparative grammar. The linguistic preoccupations of the medieval Jews, and of their teachers the Arabs, were continued by European scholars of the six- teenth century Protestant scholarship intensified interest in Hebrew, which took its place with the Latin of the Vulgate and New Testament Greek, and Ethiopian joined the scholarly repertory of known Semitic dialects Babylonian-Assyrian (Accadian) was not deciphered and identified till the nineteenth century. The family as a whole derives its name fiom Shem> the son of Noah in the Hebrew myth It is now commonly divided in the following way: East Semitic, Babyloman- Assynan (Accadian), West Semitic, (i) Aramaic, (2) The Canaamte dialects (Hebrew, Phoenician, Moabiric); South Semitic, (i) Arabic, (2) Ethiopian The Semitic languages form a unit far more closely knit than the Aryan family, and have changed comparatively little during their recorded history. As a literary language, modern Arabic stands closer to the Arabic of the Koran than does French to the Latin of Gaul in the time of Mohammed This suggests one of the reasons why the Semitic tongues have repeatedly superseded one another. Three Semitic lan- guages have successfully competed for first place, and have become current far beyond their original homes. They are * Babylonian-Assyrian, Aramaic, and Arabic The oldest representative of which we possess documents, and the first to assume international importance, was
