Learners
People who use Duolingo. We never say "users."
Courses
Courses are the core of the Duolingo learning experience, teaching a language from the learner's native language. Duolingo currently offers courses in 35+ languages. Learners can take as many as they want.
Skills
Courses are separated into sections called skills. Each skill is centered around a situation (like traveling) or a part of the language (like common phrases). Each skill covers about 30 new words and a few grammatical concepts.
Levels
Each skill has several levels. Each level focuses on teaching words and grammatical concepts in a specific context such as reading, listening, or writing.
Lessons
Skills are made up of lessons. Each lesson teaches a bite-sized chunk of the words and grammatical concepts in the skill.
Exercises
Each lesson contains about 10 exercises that let learners practice what they're learning in different ways, like translating, speaking, listening, and matching.
XP
XP stands for experience points. It's the primary currency on Duolingo. You earn XP, not points.
Streak
A streak is the number of days in a row that you've reached your XP goal.
Stories
Stories deepen language learning through mini-stories that challenge reading and listening comprehension.
Podcasts
Duolingo podcasts tell real stories that inspire listeners while deepening their language learning. Each podcast features storytelling in the learning language and narration in the listener's native language.
