Note 23 — PART I.

III. A third principle in orthography is, that no more letters ought to be employed than are necessary to represent the sound. There are probably few polished languages in which departures from this rule are not found in abundance. Reasons have been already mentioned which render it expedient to retain letters in writing many words, after the corresponding sounds have been dropped in pronouncing the same words. Quiescent letters, both vowels and consonants, are not unfrequent in Gaelic. Though these quiescent letters have no sound themselves, they are not always without effect in pronunciation, as they often determine the sound of other letters. Most, if not all, the quiescent vowels seem to have been introduced for this purpose. They ascertain the broad or the small sound of the adjoining consonants. This has been made sufficiently clear in treating of the vowels and diphthongs separately. A consonant, as has been shown, has its broad sound, both when preceded and when followed by a broad vowel; and in like manner has its small sound, both when preceded and when followed by a small vowel. If a consonant were preceded by a vowel of one quality, and followed by one of a different quality, the reader, it has been thought, might be doubtful whether that consonant ought to be pronounced with its broad or with its small sound. Hence this rule has long obtained in Gaelic orthography, that in polysyllables the last vowel of one syllable and the first vowel of the subsequent syllable must be both of the same quality[23]. To the extensive application and the rigid observance of this rule it is owing that so many diphthongs appear where one vowel is sufficient to express the vocal sound, and that the homogeneous vowels, when used in their quiescent capacity, are often exchanged for each other, or written indiscriminately[24]. From the former of these circumstances, most of the words in the language appear loaded with superfluous vowels; from the latter, the orthography of many words appears, in some respects, arbitrary and unsettled. Even a partial correction of these blemishes must be desirable. It may therefore be worth while to examine this long established canon of Gaelic orthography, with a view to discover whether it has not been extended farther than is necessary, and whether it ought not in many cases to be set aside.
