Free Language Learning-duolingo.com

Duolingo.com is a free language learning and crowdsourced text translation platform. The service is designed so that, as users progress through the lessons, they simultaneously help to translate websites and other documents.Duolingo offers extensive written lessons and dictation, with speaking practice for more advanced users. It has a gamified skill tree that users can progress through and a vocabulary section where learned words can be practiced.

Users gain "experience points" (XP) as they learn a language, such as when they complete a lesson. Skills are considered "learned" when users complete all the lessons associated with the skill. Users win one point for each correct answer, and lose one for each error, and validate the lesson when they reach 10 points.Duolingo offers Latin American Spanish, French, German, Brazilian Portuguese, Italian, Dutch, Irish, Danish and Swedish courses for English speakers, as well as American English for Spanish, French, German, Portuguese, Italian, Greek, Dutch, Russian, Polish, Turkish, Hungarian, Romanian, Japanese, Hindi, Indonesian, Korean and Czech speakers. It also offers many other combinations of languages.It is available on the Web, iOS, Android and Windows Phone 8.1 platforms
