Some of my best friends are Welsh (well, one of them anyway), and although dw i ddim yn siarad Cymraeg myself, I do try to respect them and their heritage by pronouncing Welsh placenames and hillnames correctly.
But whenever I pass the takeaway in Bala advertising Byrgyrs, Cebabau, Pitsas, and the ATS in Mach offering Teiars, Batris, Egsosts, Siocs, I do wish they could come up with something completely different, rather than just changing a few letters so it sounds the same but is "spelt Welsh"!!! 😉
(And yes, I know they're all valid Welsh words, or at least most of them appear in my Oxford Modern Welsh Dictionary).
