In my dictionary, the initial “a”s of “ceart” and “cara” are listed as short. Thereby, they should be pronounced “ceArt” and “cAra” respectively. However, when spoken, they sound like the have long vowels, so “cyAHrt” and “cAHra”. Is this some sort of dialectical difference, or is my dictionary just wrong here?
In Connemara, the short “a” (as the first vowel in “cara”) is often lengthened and has a quality close to “ea” (as in “ceart”), though I would say not exactly the same one. Still, the vowels in “cara” and “ceart” sound quite different, as the latter has a y-glide.
