With Lingo, you are never stopped by words you don’t know again. While you 
are browsing online, you can double-click on words you don’t know. Lingo 
will show you the meanings, sounds, and importance of the words. It’s a 
quick and easy way to build up your vocabulary and make reading fun!
Built on natural language processing technology, Lingo prompts users to 
learn new words and saves those to a word collection to be reviewed down the 
road. They can practice their words with automatically generated flashcards 
and quizzes.
