Note 26 — Notes

From the extracts of the oldest Irish manuscripts given by Lhuyd, Vallancey, and others, it appears that the rule concerning the correspondence of vowels in contiguous syllables, was by no means so generally observed once as it is now. It was gradually extended by the more modern Irish writers, from whom, it is probable, it has been incautiously adopted by the Scottish writers in its present and unwarrantable latitude. The rule we have been considering has been reprobated in strong terms by some of the most judicious Irish philologers, particularly O'Brien, author of an Irish Dictionary printed at Paris 1768, and Vallancey, author of an Irish Grammar, and of various elaborate disquisitions concerning Irish antiquities, from whom I quote the following passages: "This Rule [of dividing one syllable into two by the insertion of an aspirated consonant] together with that of substituting small or broad vowels in the latter syllables, to correspond with the vowel immediately following the consonant in the preceding syllable, has been very destructive to the original and radical purity of the Irish language." Vallancey's Ir. Gram. Chap. III. letter A. "Another [Rule] devised in like manner by our bards and rhymers, I mean that which is called Caol le caol, agus Leathan le leathan, has been woefully destructive to the original and radical purity of the Irish language. This latter (much of a more modern invention than the former, for our old manuscripts show no regard to it) imports and prescribes that two vowels, thus forming, or contributing to form, two different syllables, should both be of the same denomination or class of either broad or small vowels, and this without any regard to the primitive elementary structure of the word." O'Brien's Ir. Dict. Remarks on A. "The words biran and biranach changed sometimes into bioran and bioranach by the abusive rule of Leathan le leathan." Id. in voc. Fear. The opinion of Lhuyd on this point, though not decisive, yet may properly be subjoined to those of Vallancey and O'Brien, as his words serve at least to show that this judicious philologer was no advocate for the Rule in question. "As for passing any censure on the rule concerning broad and small vowels, I chose rather to forbear making any remark at all upon them, by reason that old men who formerly wrote arget silver, instead of airgiod as we now write it, never used to change a vowel but in declining of words, &c. And I do not know that it was ever done in any other language, unless by some particular persons who, through mistake or ignorance, were guilty of it." Archæol. Brit. Preface to Ir. Dict. translated in Bp. Nicolson's Irish Historical Library.
