When I took the first survey of my undertaking, I found our speech copious without order, and energetick without rules:  wherever I turned my view, there was perplexity to be disentangled, and confusion to be regulated; choice was to be made out of boundless variety, without any established principle of selection; adulterations were to be detected, without a settled test of purity; and modes of expression to be rejected or received, without the suffrages of any writers of classical reputation or acknowledged authority.

Having, therefore, no assistance but from general grammar, I applied myself to the perusal of our writers; and, noting whatever might be of use to ascertain or illustrate any word or phrase, accumulated in time the materials of a dictionary, which, by degrees, I reduced to method, establishing to myself, in the progress of the work, such rules as experience and analogy suggested to me:  experience, which practice and observation were continually increasing; and analogy, which, though in some words obscure, was evident in others.

In adjusting the ORTHOGRAPHY, which has been to this time unsettled and fortuitous, I found it necessary to distinguish those irregularities that are inherent in our tongue, and, perhaps, coeval with it, from others, which the ignorance or negligence of later writers has produced.  Every language has its anomalies, which, though inconvenient, and in themselves once unnecessary, must be tolerated among the imperfections of human things; and which require only to be registered, that they may not be increased, and ascertained, that they may not be confounded:  but every language has likewise its improprieties and absurdities, which it is the duty of the lexicographer to correct or proscribe.

As language was at its beginning merely oral, all words of necessary or common use were spoken, before they were written; and while they were unfixed by any visible signs, must have been spoken with great diversity, as we now observe those, who cannot read, catch sounds imperfectly, and utter them negligently.  When this wild and barbarous jargon was first reduced to an alphabet, every penman endeavoured to express, as he could, the sounds which he was accustomed to pronounce or to receive, and vitiated in writing such words as were already vitiated in speech.  The powers of the letters, when they were applied to a new language, must have been vague and unsettled, and, therefore, different hands would exhibit the same sound by different combinations.

From this uncertain pronunciation arise, in a great part, the various dialects of the same country, which will always be observed to grow fewer and less different, as books are multiplied; and from this arbitrary representation of sounds by letters proceeds that diversity of spelling, observable in the Saxon remains, and, I suppose, in the first books of every nation, which perplexes or destroys analogy, and produces anomalous formations, that being once incorporated, can never be afterwards dismissed or reformed.
