Quick, addictive language-learning
Duolingo promises to be “free forever” and teaches language through a series of reading, translating, speaking and listening activities that involve repeating,translating, dragging and dropping, selecting a picture to match or writing words.
PROS: Using Duolingo everyday, you’ll surely learn new vocabulary and develop some functionality in the language. Users can also translate texts and post questions to the community messaging area. Duolingo remains the most engaging language learning tool on the market.
CONS: Fluency? Pas du tout (no!). And forget about speaking skills.
