Quizlet
An effective way to expand your vocabulary

Quizlet offers a wide range of help for practising and expanding your vocabulary. Quizlet has a lot of Finnish content, although the quality level of the content varies. Some of the content producers we recommend include RekaAarnos, Ope_Johanna, MilkaMoi, HeikuraOpe, and Tarutoppola. A wide range of exercises allow learners to practise words. Words can be practised by browsing flashcards, listening to the pronunciation of words, or writing based on what you hear. Students can also create and edit word lists. In addition to the web version, Quizlet also has a mobile app. Author: a company.
