Yomitan Setup Tutorial¶
What is Yomitan?¶
Yomitan is a browser extension that allows you to look up Vietnamese words with both the meaning and the reading on web pages with ease.
Getting Started¶
Yomitan is available for both Chromium and Firefox based browsers. You can find the respective versions below.
Once installed, it will open a new tab page. Remember to change the language to Vietnamese as shown here then close it.
Acquiring Dictionaries¶
When you first install Yomitan, you need to load dictionaries into it in order to use it.
These files use the .zip extension and are not to be extracted by the user.
You can find my collection of Yomitan dictionaries below. This will have everything you need and (probably) don't need. 
duykhanh471's Yomitan Dictionary Collection.
I recommend you install the following dictionaries:
- VNEDICT
- Từ Điển Lạc Việt
- Từ điển Tiếng Việt thông dụng
- Từ điển Tiếng Việt - Hồ Ngọc Đức
- Từ điển Lạc Việt đơn ngữ
Installing dictionaries and basic usage¶
- Click on the
icon in the browser toolbar. - Click on the
icon to access the settings page. - On the left sidebar, click on "Dictionaries" and then click on "Configure installed and enabled dictionaries…"
- Click the "Import" button on the bottom.
- Here's where you select the dictionaries to import. Please only import the following.
- Please wait for the dictionaries to import. This could take a while.
- Once complete, you can test Yomitan by holding down the Shift key and hovering over Vietnamese text. Here is a sample: Tiếng Việt. It will display a pop up box displaying the definitions separated by dictionary.
Click anywhere outside of the box or press the Esc key to dismiss.
You can click the 
button to hear the word being pronounced by a native speaker.
In your browser extensions toolbar, if you click on the Yomitan logo, then on the 
icon or by using the Alt+Ins keyboard shortcut, you can access Yomitan Search, this is where you can use Yomitan as a standalone Vietnamese to English dictionary.
Pop up box size can be edited with advanced settings enabled.
A full dark mode can be enabled in the settings too.
Recommended frequency dictionaries¶
Yomitan supports the use of frequency dictionaries that tell you how common a word is.
What is a common word?
Very common: 1-10,000
Commmon: 10,001-20,000
Fairly common: 20,001-30,000
Kind of uncommon: 30,001-40,000

- Click "Manage Extensions"

Bonus: Adding Forvo extra audio source¶
You may encounter missing audio with the default Yomitan audio sources, adding Forvo will help fill in the gaps.
