JLearnIt is a thematic dictionary that allows you to learn vocabulary with a questionnaire. You can also translate text (word by word), search for incomplete words, sort the languages in alphabetical order, rearrange the order of the languages, save your score, save as HTML, and show only the languages you're interested in. Each word is rated according to frequency of use. You can choose to see only the words of a certain range of frequencies or to be asked for words of that level. You can also add and delete your vocabulary and categories, and cut/copy/paste between a spreadsheet program and JLearnIt. You can change the language and the skin of JLearnIt. You can get more information about the word on the Internet and save your configuration. JLearnIt won't ask you the same word if you know the word. It won't ask you for the word that starts with the same letters as the translation. You can edit words and set properties for this word.
