Here's a helpful glossary and guide to get you started on the Duolingo's exciting redesign of the home screen.

For a full FAQ on the new learning path, you can check it out here or take a peek at our blog.

Glossary

Path	The home screen is now designed as a path that you’ll follow step by step.
Level	The circles in the path are called levels. One level is equivalent to 1 crown level of a skill on the old home screen.
Lesson	When you tap on a level, you’ll start a lesson. There are about 5 lessons each level. The ring around the circle shows your progress through lessons for that level. Tap ‘Start’ and begin your learning journey!
Unit	Your learning path is divided into units, which introduce new concepts (e.g. “Use the present tense” or “Describe your family”).
Guidebook	At the start of each unit is a guidebook packed with grammar tips and useful phrases. The guidebook can be accessed any time, even when you complete the unit. NOTE: Guidebooks are not available for all languages.
Unity trophy	Once you complete all the levels in a unit, you’ll complete a challenge to earn your unit trophy. You’ll also have the option to earn the Legendary trophy for each unit. NOTE: Super subscribers have unlimited attempts at Legendary.
Legendary	When you complete a set of Legendary challenges, your Legendary status will apply to an entire unit.
Chests	You may see reward chests throughout your learning path. Once you reach a chest, tap to receive your gem reward. You must open the chest in order to continue further in the path.
Gems	Your gems are safe and sound! You can earn gems through chests in your learning path, earning XP, achievements, etc. Not enough gems? You can purchase a bundle of gems through the Shop tab.
XP	XP (or experience points) is still here to stay! You will earn XP by completing levels on your learning path (typically 10-30 XP). You can also earn XP through Ramp Up, Legendary challenges, and the Practice Hub.
Streak	A streak is the number of days in a row you have completed a lesson. Once you complete a lesson, your streak will increase by 1 day.
Stories	Our beloved stories and characters will be directly in the learning path! NOTE: Stories are not available for all languages. See more info here
