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 afterward dismissed or reformed.

Of this kind are the derivatives length from long, strength from strong, darling from dear, breadth from broad, from dry, drought, and from high, height, which Milton, in zeal for analogy, writes highth; Quid te exempta juvat spinis de pluribus una [Horace, Epistles, ii. ii. 212]; to change all would be too much, and to change one is nothing.

This uncertainty is most frequent in the vowels, which are so capriciously pronounced, and so differently modified, by accident or affectation, not only in every province, but in every mouth, that to them, as is well known to etymologists, little regard is to be shewn in the deduction of one language from another.

Such defects are not errours in orthography, but spots of barbarity impressed so deep in the English language, that criticism can never wash them away:  these, therefore, must be permitted to remain untouched; but many words have likewise been altered by accident, or depraved by ignorance, as the pronunciation of the vulgar has been weakly followed; and some still continue to be variously written, as authours differ in their care or skill:  of these it was proper to enquire the true orthography, which I have always considered as depending on their derivation, and have therefore referred them to their original languages:  thus I write enchant, enchantment, enchanter, after the French and incantation after the Latin; thus entire is chosen rather than intire, because it passed to us not from the Latin integer, but from the French entier.

Of many words it is difficult to say whether they were immediately received from the Latin or the French, since at the time when we had dominions in France, we had Latin service in our churches.  It is, however, my opinion, that the French generally supplied us; for we have few Latin words, among the terms of domestick use, which are not French; but many French, which are very remote from Latin.
