The _second_ class consists of those languages which are formed by agglutination. The words combine only in a mechanical way; they have _no_ elective affinity, and exhibit toward each other none of the active or sensitive capabilities of living organisms. Prepositions are joined to substantives, and pronouns to verbs, but never so as to make a new form of the original word, as in the inflected languages, and words thus placed in juxtaposition retain their personal identity unimpaired.
The agglutinative languages are known also as the Turanian, from Turan, a name of Central Asia, and the principal varieties of this family are the Tartar, Finnish, Lappish, Hungarian, and Caucasian. They are classed together almost exclusively on the ground of correspondence in their grammatical structure, but they are bound together by ties of far less strength than those which connect the inflected languages. The race by whom they are spoken has, from the first, occupied more of the surface of the earth than either of the others, stretching westward from the shores of the Japan Sea to the neighborhood of Vienna, and southward from the Arctic Ocean to Afghanistan and the southern coast of Asia Minor.
The inflected languages form the _third_ great division. They have all a complete interior organization, complicated with many mutual relations and adaptations, and are thoroughly systematic in all their parts. Between this class and the monosyllabic there is all the difference that there is between organic and inorganic forms of matter; and between them and the agglutinative languages there is the same difference that exists in nature between mineral accretions and vegetable growths. The boundaries of this class of languages are the boundaries of cultivated humanity, and in their history lies embosomed that of the civilized portions of the world.
Two great races speaking inflected languages, the Semitic and the Indo- European, have shared between them the peopling of the historic portions of the earth; and on this account these two languages have sometimes been called political or state languages, in contrast with the appellation of the Turanian as nomadic. The term Semitic is applied to that family of languages which are native in Southwestern Asia, and which are supposed to have been spoken by the descendants of Shem, the son of Noah. They are the Hebrew, Aramaeic, Arabic, the ancient Egyptian or Coptic, the Chaldaic, and Phoenician. Of these the only living language of note is the Arabic, which has supplanted all the others, and wonderfully diffused its elements among the constituents of many of the Asiatic tongues. In Europe the Arabic has left a deep impress on the Spanish language, and is still represented in the Maltese, which is one of its dialects.
