Because I am becoming ever more interested in linguistics, I am trying to learn simple phrases in as many different languages as possible, and bulletining them here in the language lab. Here's what I've got so far:

How to Say 'Hello' and 'Goodbye' in Ten Tongues

ENGLISH	Hello	Goodbye
FRENCH	Bonjour	Au revoir
ITALIAN	Buon giorno	Arrivederchi
SPANISH	Buenas dìas	Adìos
GERMAN	Guten tag	Auf wiedersehen!
CZECH	Dobrý den	Na schledanou!
HUNGARIAN	Jó napot	Viszlát
RUSSIAN	Zdravstvuyte	Do svidaniya
JAPANESE	Konnichiwa	Sayonara
CHINESE	Ni hao	Zaì jiàn

Notes:
1. The 'j' in 'bonjour' sounds like 'sh'; 'au revoir' is often pronounced as one word: "are-voir'.
2. Italian is a phonetic language: "bwOn-gyore-no"; "ah-rive-ah-dere-chee'.
3. If you live in California, you've used these Spanish phrases already. (Hint: the 'i's are stressed.)
4. Fairly phonetic in the German, I think...
5. For the Czech, I'm guessing stress on the 'y', and "na schledanou' is pronounced similarly to the russian 'da svidaniya'.
6. Like many Slavic languages, in Hungarian 'j' sounds like 'y'; otherwise, pretty phonetic.
7. Transliterated from the cyrillic alphabet, "Zdravstvuyte' sounds like "strass-veet-yuh"; you've heard 'do svidaniya' in the movies before...
8. Do I even need to bother with an explanation for the Japanese?
9. 'Ni hao' is pretty phonetic; 'zai jian' is like "sai-shin".
