When a question of orthography is dubious, that practice has, in my opinion, a claim to preference which preserves the greatest number of radical letters, or seems most to comply with the general custom of our language.  But the chief rule which I propose to follow is, to make no innovation without a reason sufficient to balance the inconvenience of change; and such reasons I do not expect often to find.  All change is of itself an evil, which ought not to be hazarded but for evident advantage; and as inconstancy is in every case a mark of weakness, it will add nothing to the reputation of our tongue.  There are, indeed, some who despise the inconveniencies of confusion, who seem to take pleasure in departing from custom, and to think alteration desirable for its own sake; and the reformation of our orthography, which these writers have attempted, should not pass without its due honours, but that I suppose they hold singularity its own reward, or may dread the fascination of lavish praise.

The present usage of spelling, where the present usage can be distinguished, will, therefore, in this work, be generally followed; yet there will be often occasion to observe, that it is in itself inaccurate, and tolerated rather than chosen; particularly when, by the change of one letter or more, the meaning of a word is obscured, as in farrier for ferrier, as it was formerly written, from ferrum, or fer; in gibberish for gebrish, the jargon of Geber, and his chymical followers, understood by none but their own tribe.  It will be likewise sometimes proper to trace back the orthography of different ages, and show by what gradations the word departed from its original.

Closely connected with orthography is pronunciation, the stability of which is of great importance to the duration of a language, because the first change will naturally begin by corruptions in the living speech.  The want of certain rules for the pronunciation of former ages, has made us wholly ignorant of the metrical art of our ancient poets; and since those who study their sentiments regret the loss of their numbers, it is surely time to provide that the harmony of the moderns may be more permanent.

A new pronunciation will make almost a new speech; and, therefore, since one great end of this undertaking is to fix the English language, care will be taken to determine the accentuation of all polysyllables by proper authorities, as it is one of those capricious phaenomena which cannot be easily reduced to rules.  Thus there is no antecedent reason for difference of accent in the two words dolorous and sonorous; yet of the one Milton gives the sound in this line,

  He pass’d o’er many a region dolorous;

and that of the other in this,

  Sonorous metal blowing martial sounds.

It may be likewise proper to remark metrical licenses, such as contractions, generous, gen’rous; reverend, rev’rend; and coalitions, as region, question.
