Quizlet is a flashcard-based learning system. Community-contributed flashcards are available for numerous languages. These vary in quality, but you can preview them to see how well they meet your needs. Each set of flashcards powers other activities: In Learn mode, you demonstrate your mastery of each word or phrase by using multiple choice to select the correct definition. There are also spelling and writing exercises. The spelling exercises can be frustrating, as they sometimes require the addition of alternate word endings that are not always pronounced by the speaker. A space-themed word game and a “Concentration”-style matching game inject some extra fun into your study time. Recent changes to Quizlet mean that you are now required to sign in to use the flashcard sets. As Quizlet is now promoting two premium plans — the modestly priced “Quizlet Plus” and the less-expensive “Quizlet Go” — you may encounter several promotions for these paid versions. We have not tried the paid tier at this time. Overall, Quizlet can be a fun, effective way to learn new vocabulary. It has the tools to help with auditory comprehension and spelling in your target language. It covers many languages, even some harder-to-find ones. However, not all of the flashcard sets are high quality.
