But besides this, it was well known that the current grammarians, and the critical philologists, had long ceased to write alike upon the English, or {vi} indeed upon any other, language. For this reason the sphere of the work became enlarged; so that, on many occasions, general principles had to be enounced, fresh terms to be defined, and old classifications to be remodelled. This introduced extraneous elements of criticism, and points of discussion which, in a more advanced stage of English philology, would have been superfluous. It also introduced elements which had a tendency to displace the account of some of the more special and proper details of the language. There was not room for the exposition of general principles, for the introduction of the necessary amount of preliminary considerations, and for the _minutiae_ of an extreme analysis. Nor is there room for all this at present. A work that should, at one and the same time, prove its principles, instead of assuming them, supply the full and necessary preliminaries in the way of logic, phonetics, and ethnology, and, besides this, give a history of every variety in the form of every word, although, perhaps, a work that one man might write, would be a full and perfect _Thesaurus_ of the English Language, and, would probably extend to many volumes. For, in the English language, there are many first principles to be established, and much historical knowledge to be applied. Besides which, the particular points both of etymology and syntax are far more numerous than is imagined. Scanty as is the amount of declension and conjugation in current use, there are to be found in every department of our grammars, {vii} numerous isolated words which exhibit the fragments of a fuller inflection, and of a more highly developed etymology. This is well-known to every scholar who has not only viewed our language as a derivative of the Anglo-Saxon, and observed that there are similar relations between many other languages (_e. g._ the Italian and Latin, the German and Moeso-Gothic, &c.), but who has, also, generalized the phenomena of such forms of relationship and derivation, and enabled himself to see in the most uninflected languages of the nineteenth century, the fragments of a fuller and more systematic inflection, altered by time, but altered in a uniform and a general manner.
