The second source of composition is of one family of roots with another. The Greek avails itself of this most abundantly, and beautifully. The English once did it freely, while in its Anglo-Saxon form, _e. g._ +boc-cræft+, book-craft, learning, +riht-geleaf-full+, right-belief-ful, orthodox. But it has lost by desuetude much of this branch of composition, which it is desirable however to resume. If we wish to be assured from experiment of the effect of a judicious spirit of Neology, look at the French language. Even before the revolution, it was deemed much more copious than the English; at a time, too, when they had an academy which endeavored to arrest the progress of their language, by fixing it to a Dictionary, out of which no word was ever to be sought, used, or tolerated. The institution of parliamentary assemblies in 1789, for which their language had no opposite terms or phrases, as having never before needed them, first obliged them to adopt the Parliamentary vocabulary of England; and other new circumstances called for corresponding new words; until by the number of these adopted, and by the analogies for adoption which they have legitimated, I think we may say with truth that a Dictionaire Neologique of these would be half as large as the dictionary of the academy; and that at this time it is the language in which every shade of idea, distinctly perceived by the mind, may be more exactly expressed, than in any language at this day spoken by man. Yet I have no hesitation in saying that the English language is founded on a broader base, native and adopted, and capable, with the like freedom of employing its materials, of becoming superior to that in copiousness and euphony. Not indeed by holding fast to Johnson's Dictionary; not by raising a hue and cry against every word he has not licensed; but by encouraging and welcoming new compositions of its elements. Learn from Lye and Benson what the language would now have been if restrained to their vocabularies. Its enlargement must be the consequence, to a certain degree, of its transplantation from the latitude of London into every climate of the globe; and the greater the degree the more precious will it become as the organ of the development of the human mind.
