Us nords have nine vowel letters:
- a e i
- o u y
- æ ø å
and they all are just themselves for a name. Like e isn't "c with a line" any more than q is "o with a leg".
They're also all monophthongs, which is hard to communicate to anglophones who pronounce their vowel letters overwhelmingly as diphthongs. E.g. anglos probably read the vowel letters as
- ey i ay
- åo ju way
- ??? ??? ???
There's an æøå song which might help.
