Thank you! I think once I read something about the no that become a question at the end...
thanks for let me remember it!
:)

I am not too much into informal Japanese since all textbook I have "worship" the ですます. Can you actually add the の directly to a name to make it as a question? I thought you still need the copula だ which in this case becomes な. クリスマスライブなの. I think it actually might be a possessive. As a title of a blob it might introduce what the blob is about. Not knowing what this Christams live is and what the blob is about tho we can only throw on the plate a huge amount of wild guesses.

Don't they all? My Class teacher actually goes as far as to pretend that the "informal" part of her language does not exist..

I didn't learn anything about informal from textbooks, just from copying the way my friends speak.

Probs not - just me being a n00b..

クリスマスライブなの means, depending on inflection of the voice, "It is a Christmas concert" or "Is it a Christmas concert?" Sort of like あ、クリスマスライブなんだ。

When speaking informally, you can drop だ often in this situation. I would if I were asking something like this of my friends. If a friend of mine, Yoshino, invited me to a big New Years Eve event her father got her tickets for but didn't tell me what it was at first, I'd immediately ask 紅白なの？ (紅白歌合戦 is the name of a very famous end-of-year "concert".)

And what's a "blob"?

What class are you in? That could be pretty important in her decision not to refer to plain form.

I think the word that Chryuop might have been aiming for is blurb, as in a short section of text.

Woop! I was right :D

Its only 2nd Year class and half the people can't even use the first line of Hiragana.. I only go for speaking practise since I have no nearby Japanese speakers of my level. :)

No, I mean for each. Maybe ちゃん can be interpreted as adding "-poo" to somebody's name, or "honey". 君 I don't know, maybe little guy, son, junior, young master. Possibilities might be endless. But either way you can't translate things like these 1:1 since they're cultural, but you can approximate. Although I do think it's a bit goofy to use these in English unless there's good reason for it.

Why would you wanna use a Japanese name suffix in English when they do not exist in this language?

I wouldn't, but when it comes to translating some content from j to e, some have been known to. That's what the topic is about, after all.
