It's the blas isn't it?
Is it just me or is the b in Araibis broad?
Yes, it does sound broad.
Yes. It's making it harder for me to learn to spell it. The i before the b is noticeable but not enough to suppress the idea that the final syllable is "-bais" so I was typing "Arabais". The only antidote is repetition.
Is fearr Araibis bhriste, ná Béarla cliste. ;-)
