“ The Teutonic languages form a distinct and well-defined group of the Indo-European family. Their nearest affinities are on the one side with the Celtic and Italic (Latin, &c.) languages, and on the other with the Slavonic and Baltic languages. In regard to the fundamental distinction, however, by which the Indo-European languages as a whole fall into two main divisions, namely according to the treatment of certain guttural and palatal consonants, the Teutonic group belongs definitely, together with Celtic, Italic and Greek, to the western of these divisions. ”
