Perhaps one of the most remarkable characteristics of the Semitic family of speech is its conservatism and resistance to change. As compared with the other languages of the world, its grammar and vocabulary have alike undergone but little alteration in the course of the centuries during which we can trace its existence. The very words which were used by the Babylonians four or five thousand years ago, can still be heard, with the same meaning attached to them, in the streets of Cairo. _Kelb_ is "dog" in modern Arabic as _kalbu_ was in ancient Babylonian, and the modern Arabic _tayyîb_, "good," is the Babylonian _tâbu_. One of the results of this unchangeableness of Semitic speech is the close similarity and relationship that exist between the various languages that represent it. They are dialects rather than distinct languages, more closely resembling one another than is the case even with the Romanic languages of modern Europe, which are descended from Latin. Most of the Semitic languages--or dialects if we like so to call them--are now dead, swallowed up by the Arabic of Mohammed and the Qorân. The Assyrian which was spoken in Assyria and Babylonia is extinct; so, too, are the Ethiopic of Abyssinia, and the Hebrew language itself. What we term Hebrew was originally "the language of Canaan," spoken by the Semitic Canaanites long before the Israelitish conquest of the country, and found as late as the Roman age on the monuments of Phoenicia and Carthage. The Minæan and the Sabæan dialects of southern Arabia still survive in modern forms; Arabic, which has now overflowed the rest of the Semitic world, was the language of central Arabia alone. In northern Arabia, as well as in Mesopotamia and Syria, Aramaic dialects were used, the miserable relics of which are preserved to-day among a few villagers of the Lebanon and Lake Urumîyeh. These Aramaic dialects, it is now believed, arose from a mixture of Arabic with "the language of Canaan." On the physical side, the Semitic race is not so homogeneous as it is on the linguistic side. But this is due to intermarriage with other races, and where it is purest it displays the same general characteristics. Thick and fleshy lips, arched nose, black hair and eyes, and white complexion, distinguish the pure-blooded Semite. Intellectually he is clever and able, quick to learn and remember, with an innate capacity for trade and finance. Morally he is intense but sensuous, strong in his hate and in his affections, full of a profound belief in a personal God as well as in himself.
