  • What is the best and easiest way to learn Dutch
    Give https://busuu.com/ a go, I think it does a much better way of explaining words and grammar than Duolingo. Good luck! Source: almost 4 years ago
  • Similar website as Lengalia for Italian?
    When I was starting out I used a subscription to Busuu and thought it was pretty good. They had listening exercises, vocab exercises, grammar/conjugation, and test exams. There's also a community feature where native speakers can correct some of the exercises you do (and vice versa). Source: almost 4 years ago
  • 30F Looking for a language partner to practice basic French. I can help with Portuguese (BR)
    I have been studying French for a few years (I still don't feel I would be very beneficial to you unfortunately, however) and a good place to look for language partners that I have found is busuu.com . A big section of it is connection to others learning your native language that speak your learning language. Just fyi if you want that info. (: Good luck!! Source: about 4 years ago
  • Duolingo is overrated
    Then I've tried Busuu premium, which is considerably better than Duolingo - at the very least tries to teach you grammar, and the video contents are really well produced. For an absolute beginner it is great! Source: about 4 years ago
