What's the name of the "O" with a diagonal stripe through it which you get in Norwegian (and other Scand.)languages?

I've never seriously studied Norwegian, much to my dad's chagrin... so if it has a name of its own (i.e. w=doubleyoo), I don't know it.

I *can* give you, however, a vague approximation of the sound that it represents. Stick your lips out like you're going to say "oooo", and say "eeee" through those lips. I recommend trying it alone - if someone sees you practicing it, you'll develop a reputation that you may or may not deserve...

Cerealkid, you crack me up! But--don't yew know it's double-yew?

Johnjohn, lovely to see you here. Martin Ramsch calls it, helpfully:

capital O, slash     Ø

this looks like it has most of the answers:

ø sounds a lot like an umlaut - ü

fascinating stuff!

For another link about Norwegian alphabet and pronunciation:
http://library.thinkquest.org/18802/norwlang.htm?tqskip1=1&tqtime=0729

These three characters are Æ (æ), Ø (ø) and Å (å) and they
come in that order right after Z in the alphabet. They are
pronounced as the vowels in "sad", "bird" and "four".
Computer keyboards sold in Norway have three more keys
than standard English keyboards, one extra key for each extra
letter.

Just to keep it going -

ø means "island
å means "creek"

so, "island in the creek, in Danish (and also in Norske, I think) would come out as, "ø i det å"

I thought you needed to know that

I knew I'd get MORE than the answer here! One of the websites mentions "sociolects" (cf. dialects), which is new on me - I kind of like the notion of a Mitford-like "people who talk like us, dear". Perhaps it's like a broader type of shibboleth....
