## What is CJKI Vietnamese?

This CJKI Vietnamese-Japanese Dictionary, which covers general vocabulary, has been optimized for the convenience of iPhone users. It contains enough Japanese equivalents translation and other information to give the user an in-depth understanding of Vietnamese words and phrases without cluttering up the screen. 

This dictionary caters to the needs of learners by providing Vietnamese example sentences, as well as synonyms and antonyms when appropriate. As is well known, a very large portion of the Vietnamese vocabulary consists of Sino-Vietnamese words and compounds, such as thế giới (世界). To facilitate more efficient learning of such words, this dictionary provides the Chinese character equivalents of these words, though the Chinese-based writing system in Vietnamese was abolished in the early 20th century. 
This dictionary is a collaborative effort between The CJK Dictionary Institute, Inc. and Yutaka Inoue (based in Viet Nam), chief editor of TỪ ĐIỂN ĐIỆN TỬ TỔNG HỢP IN LẦN THỨ 2 (越日・日越総合電子辞典 第二版), who is continually working on bringing the dictionary up to date and expanding it.

### 5/5 — iPhone / iPad OS 17.3.1 でちゃんと動作しています

*2024-03-05*

ベトナム語学習において非常に有用なアプリ。
訳語のページをコピーできるのでメモ帳などにペーストして見返しようにしています。

iPadで使うことが多いので、⌘(cmd)キー長押し時のショートカット表示に対応できるようにして、ベトナム語モードと日本語モードをショートカットで切り替えられるようにして欲しいです。

controlキー + ←→ での切り替えを希望します。

あとは、デジタル書籍のようにしおり機能をつけていただき、マークした単語を一覧で見れるような機能改善を期待します。

iPhone版では検索窓および言語切り替えボタンを画面下に配置し、検索時にiPhoneを持ち帰る必要がないようにすると操作性がさらに良くなると思います。
