Vietnamese-Vietnamese Dictionary (VTuDien)

VTuDien’s Vietnamese-Vietnamese Dictionary is a free web dictionary for looking up Vietnamese words using Vietnamese explanations. It suits learners who can already read some Vietnamese and want clearer meaning, nuance, and usage without relying on English.

You search a word on the main Viet–Viet page and get entries that often include part of speech labels, short definitions, and example lines. Many entries also show additional definition blocks from different sources, which can help you compare wording and sense.

It can be handy when you are reading Vietnamese articles or books and want a quick monolingual check. Some pages also offer a “save to remember” style option for tracking words, but it is still primarily a lookup tool, not a structured course.

The main downside is that it is not designed to teach Vietnamese from zero. Definitions use Vietnamese shorthand and dictionary-style formatting, so complete beginners will likely struggle without a bilingual dictionary or teacher support.
