Here's a question about English accent comparison. It's about the differences in phonemic inventory of Irish Supraregional compared to RP.
Is the Irish English vowel in the lexical set FACE /e:/ a difference in phonemic inventory (compared to RP's diphthong in the same lexical set) or is this just a different realisation?
(Compared to e.g. RP's diphthongs /ɪə, eə, ʊə/ vs. GA in ‘beard’ /bɪrd/, ‘fare’ /fer/, ‘dour’ /dʊr/ which are said to be differences in phonemic inventory)
Just as GA is "lacking" in RP's diphthongs, can't the same be applied for Irish Supraregional vowel in the FACE set, i.e. it's lacking the /eɪ/ diphthong ? (or RP lacking the /e/ in such ph. environment - as far as I'm concerned, /e/ can only appear in RP in the diphthong /eɪ/)
Thank you, anyone who can clarify.
