So far have I been from any care to grace my pages with modern decorations, that I have studiously endeavoured to collect examples and authorities from the writers before the Restoration, whose works I regard as _the wells of English undefiled_, as the pure sources of genuine diction. Our language, for almost a century, has, by the concurrence of many causes, been gradually departing from its original Teutonick character, and deviating towards a Gallick structure and phraseology[2], from which it ought to be our endeavour to recall it, by making our ancient volumes the ground-work of style, admitting among the additions of later times only such as may supply real deficiencies, such as are readily adopted by the genius of our tongue, and incorporate easily with our native idioms.

But as every language has a time of rudeness antecedent to perfection, as well as of false refinement and declension, I have been cautious lest my zeal for antiquity might drive me into times too remote, and crowd my book with words now no longer understood. I have fixed Sidney's work for the boundary, beyond which I make few excursions. From the authors which rose in the time of Elizabeth, a speech might be formed adequate to all the purposes of use and elegance. If the language of theology were extracted from Hooker and the translation of the Bible; the terms of natural knowledge from Bacon; the phrases of policy, war, and navigation from Raleigh; the dialect of poetry and fiction from Spenser and Sidney; and the diction of common life from Shakespeare, few ideas would be lost to mankind, for want of English words, in which they might be expressed.

It is not sufficient that a word is found, unless it be so combined as that its meaning is apparently determined by the tract and tenour of the sentence; such passages I have, therefore, chosen, and when it happened that any author gave a definition of a term, or such an explanation as is equivalent to a definition, I have placed his authority as a supplement to my own, without regard to the chronological order, that is otherwise observed.

Some words, indeed, stand unsupported by any authority, but they are commonly derivative nouns or adverbs, formed from their primitives by regular and constant analogy, or names of things seldom occurring in books, or words of which I have reason to doubt the existence.
