Lingualy is a free Google Chrome extension designed to help you learn a new language while browsing the web. With Lingualy installed anytime that you come across a new word you can double-click on it to hear it pronounced, read a translation, and read a definition. The words that you double-click are added to your Lingualy account where you can review them in a quiz format. Watch a short overview of Lingualy in the video below.
Applications for Education
Lingualy supports English, Spanish, French, Hebrew, and Arabic. You could have students use Lingualy while reading news articles in the language that they're trying to learn. That would provide some current context for language lessons.
