(a) In compound words a diphthong may occur in the second syllable—e.g., urlaḃra (pr. oor-loura).
(b) In Munster the ḃ in the termination of the 2nd pers. pl. of the past tense—viz., aḃar is usually pronounced like a “w,” hence the long ú sound is not developed. The final r of this termination, as likewise of that of the 1st pers. pl.— viz., amar is pronounced slender.
(c) In Connaught the adjectival termination, -ṁail is frequently pronounced in two syllables (like, u-wil), but the pronunciation given above is also used.
63. When Ḃ or ṁ is preceded by a liquid, and followed by a broad vowel, the -Ḃ, or -ṁ and the following vowel is pronounced ú.
This really arises from the development of a “helping vowel” between the liquid and the ḃ or ṁ, so that the aspirated letter comes between two vowels, and the resulting sound is ú as in the previous rule. For example—searḃ is pronounced searaḃ; so that searḃas is practically searaḃas, i.e., searús.

(a) greannṁar=greannúr, but this is irregular because -ṁar as a termination of an adjective is pronounced like “war” or “u-war”—e.g., ceolṁar, fonnṁar, &e.
64. A short “o” (accented) when followed by a protected l or m, or by ḃ, ḋ, ġ, or ṁ+a vowel or liquid, gets the sound of the diphthong “ou.”
