Welcome, language learners. If you've clicked on this listicle, it is because you have fallen into the downward-spiral trap that is Duolingo. "Download the app," they said. "It gamifies language-learning so it doesn't feel like a chore," they said. So, you did, and it really was fun. Depending on the language you choose to learn, there are all sorts of games, podcasts, and interactive stories that you can use to help you quickly get the gist of a language. There are also so many languages to choose from, including fake ones like Game of Throne's High Valyrian and Star Trek's Klingon.
It was all fun and games until you accidentally skipped a lesson, breaking your learning streak. Then, you began getting notifications from the little green owl, urging you to pick back up from where you left off. With each passing day, the messages grew more and more threatening, until you caved out of fear for your life. Now, you have a 895 day streak in Spanish. Congrats!
