Well, I just had to bring that up, didn't I? It turns out Welsh pronunciation is a giant bloody mess... Well, the spelling is supposed to be almost completely phonetic, but those phonemes have quickly gone from funny to headache-inducing. For example, I'm reading 8 rules for deciding if a vowel is long or short, each rule pretty much an exception to the previous one, in the form of "in the ending syllable vowels are long, except if the ending consonant is ll, ff, or dd" (yeah).
