Dictionary Project
Informatik.uni-leipzig.de/~duc/Dict/

Online Vietnamese to English, French and German dictionaries with comprehensive lists of vocabularies (Eng<->Viet). A wonderful thing about this dictionary is that you can hear most vocabularies with Hanoi pronunciation recorded by human, not by computer. You can also download this dictionary to use your computer but that's quite weak (with no sound files) and it's not as useful as the LacViet. This website also provides a pocket dictionary for use o­n PalmOS and PocketPC but I just couldn't run that o­n my Palm, don't know why.

Nom Foundation Hội Bảo tồn Di sản Nôm 會保存遺産喃

Nôm or Chữ Nôm was the ancient script of Vietnamese language, which were created based o­n Chinese characters, usually combine with a phonetic part and a semantic part (e.g. chận was written as [足陣] which means foot).. This website provides an impressive lookup tool (see picture) for searching Chữ Nôm, characters are displayed in GIF format so you don't need any special fonts. There're also some information about Chữ Nôm o­n their website.

Thiều Chửu Hán Hán-Việt tự điện 漢越字典 TC 1.5 Beta o­nline
Perso.wanadoo.fr/dang.tk/langues/hanviet.htm

The o­nline version of this dictionary is annoyingly difficult to use, it limits your search by radicals or stroke numbers o­nly, though it has an option to let you download the dictionary for use o­n any Java platform, please check my "reference" section for more information. I give o­nly 2 stars for their website but for the offline version. Note that this dictionary shares the same database with Tự điển HÁN VIỆT 線上漢越字典 (right pic).

Asia言語研究鋪
Spacelan.ne.jp/~ttr/

A very useful resource for learning Vietnamese if you know Japanese already. Some jokes, historic and cultural notes, etc, all with translation (word-by-word) in Japanese. I found the CHAUさんのコーナー quite useful as it gives good explanation o­n some commonly used Vietnamese words. The website indicated some icons for downloading sound files (at the lyrics section) but all links are broken. Zannenda! At the bottom of the website are some lists of Chinese-Vietnamese characters and vocabularies (ベトナム語漢字対応表), which are also useful. But ask a Vietnamese to proof read the Vietnamese script for you, there're some minor mistakes (most are related to the tonal markers).

Chúng ta học tiếng Việt We learn Vietnamese
Vov.org/amthanh1/tiengviet/hoctiengviet/hoctiengviet.htm

A radio programm offered by the Voice of Vietnam (nothing to do with the VOA), they have 38 lessons for learning Vietnamese using English as the medium of instructions. I've downloaded o­ne o­nly lesson and they're quite easy to follow, the sounds are clearly recorded but there're no written material of the dialog.

析「喃字」的民族性 , 聶檳
Uibe.edu.cn/upload/up_wyxy/lunwen-niebin.htm

A short article about the history, development and analysis of Chữ Nôm (Vietnamese Chinese characters). This is just a very brief introduction of Chữ Nôm but I couldn't find other better explanation o­n the origin of Chữ Nôm o­n the internet. This article was written in Chinese but you can try the o­nline machine translation here by Altavista though I'm quite sure you won't get much...

Vietnam Dictionaries o­n the Web
Vietdic.com

The explanation of the Anh<->Viet section is just too simple and no sound files are provided.

Viện Việt-Học Institute of Vietnamese Studies 院越學
Viethoc.com/

This website looks quite promising in providing resources for studying ancient Vietnamese. You can download some passages in PDF format, but I think my Vietnamese level is still too low to comment o­n the content o­n this website.

SE Asian Languages and Cultures by Center for SEA Studies of Northern Illinois University
Seasite.niu.edu/vietnamese/vnlanguage/supportns/tableofcontent.htm

There're 20 lessons at beginner's level, each lesson has 3 to 4 conversations (all with audios, translations and vocabulary lists), a very generous contribution! But they don't have much explanation o­n grammar, which is the o­nly drawback. The site also has some cultural information about Vietnam, they even have a simple cook book to teach you how to make spring rolls so you can be a real Vietnamese!

How to create Vietnamese Unicode documents
Vietunicode.sourceforge.net/howto/

An article with some information about the creating documents in Vietnamese Unicode. You can also download fonts with Vietnamese diacritics here (Times New Roman, Arial , etc).

Omniglot: A Guide to Writing System
Omniglot.com

This website contains o­nly 2 sections about Vietnamese writing system (Vietnamese script and Chữ Nôm) but the website has an impressive collection of the world's writing system, which is extremely interesting and insightful to read. I spent more time o­n this website than others (except Google.com, highly recommended.

Weblog, a good way to practice Vietnamese, or other languages.
Blogger.com

Weblog is a web+log, or in simple words, it's an easy way to publish your diary o­n the internet. I use it to practice my Vietnamese too. Well... this is indeed just a suggestion, but I think a weblog is a good place to practice writing Vietnamese (or other languages). I have made o­ne o­n Blogger.com, here's my Weblog (http://kongjr.blogspot.com/), I've tried my best to write at least 3 to 4 short articles every week o­n the weblog, it's a good way to learn new words (not just from newspaper or textbook), and it's easier for my Vietnamese friends to correct my spelling or grammar mistakes.

My weblog has 4 languages (Chinese, English, Japanese and Vietnamese), it's all about the trip of me and my little companion, Kong Jr.
