If it appear, then, that the vowel sounds in speech are perpetually varying in the mouths of different speakers, from causes which either elude our search, or, when discovered, are seen to be of small importance, may we not judge that it would be equally vain and improper to attempt to make _Writing_ follow all these minute variations; and that, however it may happen that the same vowel sound may be represented in many instances by different letters, and different vowel sounds by the same letters, yet this disagreement between _Speech_ and _Writing_ must be connived at, for the sake of preserving some degree of uniformity, where alone it can be preserved, in the _written language_? If it appear, again, that the variations from the established analogy which are made on the articulations are less frequent, and proceed from causes obvious and cogent, ought not these variations to be exhibited in writing, for preserving that general correspondence between the written and the spoken language which ought to be preserved, as far as the limited powers of letters will permit, and without which the words I speak and those I write do not belong to the same language?
One exception from this principle seems allowable in the case of quiescent consonants. It may be inferred, from the practice of all living languages, that consonants whereof the corresponding articulations have been suppressed in speaking may yet be retained with propriety in writing, when they are requisite to point out the derivation of vocables, or the radical part of declinable words. But this exception ought to be allowed only to a moderate extent, for the reasons already assigned; to which it may be added, that the far greater part of the suppressed articulations can be easily discovered and retraced to their roots, without any index in the _written_ any more than in the _spoken_ language to point them out. { 28}
These observations being premised, I shall proceed to explain the present state of Gaelic Orthography, and shall endeavour to assist the reader in forming a judgment of its merit, and how far it may admit of improvement.
I. It may be laid down as one settled principle in orthography, that each letter or combination of letters in the written language ought always to denote one and the same sound. From the explanation that has been given of the powers of the letters, it may be seen how far this principle has been regarded in the Gaelic. Though almost every one of the letters represents more than one sound, yet there is an evident affinity between the several sounds of the same letter. And it may be readily allowed that less confusion and inconvenience follow from exhibiting a few kindred sounds by the same letter, than would have taken place had the characters been multiplied to such a degree as that a separate one could have been appropriated to each minute variety of sound.
