Vietnamese-Vietnamese Dictionary

VTuDien's Vietnamese-Vietnamese dictionary is a free word lookup website for learners who can already read basic Vietnamese. Instead of translating into English, it explains words in Vietnamese, so it is most useful once you have some foundation and want to think more directly in the language.

Each entry gives you Vietnamese definitions and usually labels the word class, such as noun or verb. Many pages also include extra example lines or related uses, which helps when a word has several meanings. Because it is part of a larger dictionary site, you can also move between Vietnamese and bilingual dictionaries if you need a quick cross-check.

What it does well is simple reference work. If you want to confirm meaning, usage, or how a word is categorized, it is fast and free. What it does not do is teach in a guided way. There are no lessons, beginner-friendly explanations, or speaking practice, so it works better as a support tool than as a main study resource.
