What Is Lernu and How Can You Use It to Learn Esperanto?

Lernu (lernu.net) is a multilingual website built specifically for learning Esperanto, the international language. It is not a general-purpose language app like Duolingo; it exists only for Esperanto. If you want a free, structured starting point for the language, Lernu is one of the most established places to begin. It suits complete beginners who want courses, a dictionary, and translation help in one place, and it also gives more advanced learners reading material and community features.

What Lernu actually is

Lernu describes itself as "a multilingual site for learning the international language Esperanto." Two things follow from that:

• It is Esperanto-only. You will not find Spanish, French, or Japanese courses here. Every course, text, and exercise is about Esperanto.
• It is multilingual in interface and support. The site is designed so that people speaking different native languages can use it, which matters because Esperanto learners come from everywhere.

The site's own keywords point to the main functions: learn Esperanto, Esperanto course, Esperanto dictionary, Esperanto translation, and community. So think of Lernu as a learning hub rather than a single course.

The main resources on Lernu

The exact set of courses and features can change over time, so treat the list above as categories to look for rather than a fixed menu.

How a beginner can start

1. Open lernu.net. The site is designed to be usable from a browser; you do not need to install anything to look around.
2. Set your language. Because Lernu is multilingual, choose the interface and support language you are most comfortable with. This affects how instructions and translations are shown.
3. Pick a course by level. Start with a beginner or introductory course rather than jumping into advanced reading. If a course feels too hard in the first lesson, that is a signal to move down a level, not to quit.
4. Work through the first lessons. Do the exercises as they come. Esperanto's regular grammar means early lessons tend to move quickly, so expect visible progress in the first sessions.
5. Use the dictionary alongside the course. When a word is unfamiliar, look it up rather than guessing; the dictionary is there for exactly this.
6. Set up an account if you want to track progress or join the community. Account setup is a common friction point, so if you only want to try a lesson, you can often read first and register later.

Expected result: after the first few lessons you should be able to recognize basic sentence patterns and a core set of words, and you should know whether Lernu's course style works for you.

When Lernu is enough on its own, and when it is not

Lernu can carry you a long way as a beginner because it combines a course, a dictionary, and translation help in one place. That combination is hard to beat as a free starting point.

It is less suited to:

• Speaking practice. A website cannot replace conversation. If your goal is fluent speech, you will eventually need real conversations, whether online or in person.
• Exam-style or highly structured certification paths. Lernu is a learning site, not an accredited program.
• Learners who need heavy gamification. If you stay motivated only through streaks, points, and app-style rewards, a general language app's format may hold your attention better, even though it will not be Esperanto-specific.

A practical approach: use Lernu for structured study and vocabulary, and add conversation practice separately once you can form basic sentences.

Common issues to expect

• Language selection confusion. With many languages available, it is easy to end up with an interface or course support language you did not intend. Check your language setting early.
• Choosing the wrong course level. Beginners sometimes start too high and get discouraged. Start lower than you think you need.
• Account setup. If registration feels like a barrier, explore the site first and register when you are ready to commit to a course.
• Expecting a general language app. Lernu will not teach you any language other than Esperanto. That focus is the point, but it surprises some first-time visitors.

The short version

Lernu is a free, Esperanto-only, multilingual learning site with courses, a dictionary, translation help, and community features. For a complete beginner, the sensible path is: open lernu.net, set your language, choose a beginner course, work through the first lessons with the dictionary at hand, and register when you want to track progress or join the community. It is an excellent starting point; it is not a substitute for real conversation practice later on.
