Understanding Duolingo’s Approach to Learning Korean

Duolingo is a popular language-learning app known for its gamified approach to education. It provides a range of exercises, from matching words to filling in blanks, aimed at building vocabulary and understanding grammar. Here’s a closer look at how Duolingo facilitates Korean language learning:
Key Features of Duolingo for Korean
- Interactive Lessons: Duolingo’s lessons include a mix of reading, writing, listening, and speaking exercises. This helps in developing a well-rounded understanding of the language.
- Gamification: The app uses points, levels, rewards and competition from other users to keep learners motivated. This gamified approach makes the process engaging and less monotonous.
- Daily Goals: Duolingo encourages daily practice through its goal-setting feature, which helps learners build and maintain consistent study habits.
- Speech Recognition: The app includes exercises for speaking, allowing users to practice pronunciation and conversational skills.
Learning Korean on Duolingo: What to Expect

Duolingo provides a structured path through its “tree” of lessons, but the time required to finish the course can vary depending on how much time you spend using the app.
How Long Will It Take To Finish The Course?
On average, Duolingo recommends spending around 20-30 minutes per day learning a language. Based on this, you should expect the following time scales:
| Proficiency Level | Estimated Study Time per Day | Total Time Required |
|---|---|---|
| Beginner Course | 20-30 minutes | 3-6 months |
| Conversational Course | 30-60 minutes | 6-12 months |
| Advanced Course | 60 minutes to 1 hour | 1-2 years |
Factors Affecting Learning Time

Several factors can influence how quickly you learn Korean on Duolingo:
- Consistency: Regular practice is crucial. The more consistently you use Duolingo, the faster you progress.
- Prior Knowledge: If you already have some background in Korean or another language with similar features (such as Japanese), learning the language will be easier and quicker.
- Previous Experience Learning a Language: Even if you haven’t learned a similar language to Korean but have studied other languages in the past to an advanced level, this will help you understand how to pick up a language so can make studying Korean easier.
- Diverse Learning: While Duolingo is a powerful tool, using it with other resources like textbooks, language exchange, or media consumption (e.g. Korean dramas and music) enhances and accelerates learning. You should only use this app as a supplement to your other studies.
What You’ll Learn on Duolingo

Duolingo’s Korean course is divided into several topics, each designed to build upon the last. Here’s a general outline of what you can expect to learn at different stages:
1. Basics and Greetings
- Alphabet and Pronunciation: Learning Hangeul, the Korean alphabet, is the first step. Duolingo provides exercises to help you master reading and writing Korean characters.
- Basic Phrases: You’ll learn common greetings and polite expressions such as “안녕하세요” (annyeonghaseyo – Hello) and “감사합니다” (gamsahamnida – Thank you).
2. Grammar and Sentence Structure

- Basic Sentence Formation: Introduction to Korean sentence structure, which typically follows a Subject-Object-Verb (SOV) order.
- Tenses and Particles: Learning about different tenses (present, past, future) and particles used in Korean sentences.
3. Vocabulary Building
- Everyday Vocabulary: Words and phrases related to daily activities, such as food, travel, and shopping.
- Essential Verbs and Nouns: Building a foundational vocabulary to help with basic conversations.
4. Intermediate Topics
- Complex Sentences: Understanding more complex sentence structures and conjunctions.
- Cultural Context: Exposure to Korean culture through language use in various contexts.
5. Advanced Practice
- Conversational Skills: Practicing more natural and fluid conversations.
- Nuanced Vocabulary: Learning advanced vocabulary and idiomatic expressions.
Measuring Progress

It’s important to track your progress to understand how well you’re learning Korean. Here are some ways to measure your progress with Duolingo:
- Skill Levels: Duolingo uses a skill tree where you can see your progress in different areas (e.g. greetings, travel). Progress in these skills indicates your advancement in these topics.
- Practice Streaks: Maintaining a daily practice streak helps gauge your consistency and dedication.
- Language Proficiency Tests: Periodic testing, whether through Duolingo’s quizzes or tests from other providers, can give you a sense of your overall language skills.
Tips for Maximizing Your Learning with Duolingo
- Set Realistic Goals: Define what you want to achieve with your Korean learning (e.g. conversational ability, reading comprehension) and set realistic goals with subgoals to help you achieve it.
- Use Duolingo Daily: Consistency is key. Aim for daily practice to build and reinforce your skills.
- Engage with Korean Media: Supplement your learning with Korean dramas, music, and books to improve your listening and comprehension skills.
- Practice Speaking: Use Duolingo’s speaking exercises to practice pronunciation, but also seek opportunities for real-life conversation with native speakers.
- Join Duolingo Communities: Participate in forums or social media groups to share experiences, ask questions, and get support from other learners.
Is Duolingo Good For Learning Korean?

Whilst I wouldn’t recommend using Duolingo as your main study resource for Korean, it is a good way of helping you build a daily habit. With its streaks and leagues, the gamified and competitive nature of the app is pretty effective in keeping you coming back to Duolingo each day.
That being said, there really is no shortcut for language learning, especially for a language as difficult to learn as Korean. Although Duolingo is a fun way of getting into language learning, it’s simply not comprehensive enough to provide you with everything you need to know to be fluent.
In fact, I would argue that no one source is comprehensive enough to learn Korean – the more diverse your learning resources are (without getting overwhelmed!), the better.
Can I Become Fluent With Duolingo’s Korean Course?
It’s important to note that you most likely won’t be fluent by the time you finish the Duolingo course. It’s usually best to use multiple learning sources that give you diverse experience in listening, reading, writing and speaking.
You also need to build an understanding of Korean grammar and learn thousands of vocabulary words. Realistically, learning Korean takes thousands of hours and requires a lot of perseverance as it’s quite a difficult language.
While Duolingo can teach you a little of all these skills, it’ll only take you so far. It’s a good idea to use Duolingo alongside other resources.
So Why Isn’t Duolingo Effective For Learning Korean?
There are a few major reasons Duolingo isn’t the most effective resource out there.
1. Nonsensical Sentences

This might appeal to some, but the app and website include a lot of sentences that would never be used in real life. This isn’t just for the Korean course, it happens for all other languages too.
Whilst some of the sentences do make me chuckle and they are memorable (e.g. “The elephant digs a pond” or the slightly more horrific “The chicken orders chicken soup”), there’s only a very very small chance (hey, can’t rule either out completely!) that I would ever need to use them in real life.
2. No Real Active Recall
There is little to no active recall because you either listen to or read a sentence in Korean and translate it into English by filling in the blanks rather than typing the translation into a blank search box.
When you translate the other way (i.e. from English to Korean), the same thing applies.
Plus, unless you complete all lessons on a harder difficulty (Legendary), you can click on a word in the sentence you need to translate and it’ll just tell you the translation for that word.
Essentially, Duolingo tells you all the answers and doesn’t require you to think much about the answer yourself.
3. Limited Explanations
Unless you pay for premium (which I would discourage), the app only includes very limited explanations for specific grammar points or marking particles. Nor does it really explain the honorific system (beyond a very basic explanation), which is a fundamental part of the Korean language and has a massive impact on the vocabulary and sentence endings you choose to use.
Whilst the desktop website might be a bit more comprehensive, most learners will be using the app.
You could argue that this is a good thing: you’re learning like a baby, soaking everything up like a sponge. But, coupled with the other limitations of the app (especially no active recall and the nonsensical sentences), it doesn’t force you to speak naturally, as would usually be the next step for children who are learning a language.
4. Loads of Ads
Ads on Duolingo have got worse as years have gone by. If you don’t pay the monthly fee, you’ll see at least one advert after each lesson. This is also usually followed by an ad (probably about 30 seconds) for Duolingo Premium, which doesn’t mute automatically even if you’ve muted the previous advert.
5. Highly Repetitive (Especially At The End Of The Course)

Whilst the repetition throughout the modules is fairly important to help you memorise vocabulary and grammar points, this continues even after you complete the course and get onto the “Daily Refresh” section. This section is essentially just a few lessons for you to complete daily so everything stays fresh in your mind.
Except it really hasn’t been used in this way by Duolingo.
The three sections of the course covers a range of topics, including talking about your dreams, describing animals, expressing your feelings, etc. Yet when you get onto the daily refresh section, more or less the same 30 prompts – plus a handful of “stories” – are given day in, day out.
Unless, that is, you try to complete a lesson on Legendary, in which case the app throws up completely different sentences and vocab that you haven’t seen in years.
Hopefully this turns out to be a bug and gets fixed, but at the moment it doesn’t provide learners with the impetus to continue using the app after they’ve finished the course.
The Time Can Vary
Learning Korean with Duolingo can be an engaging way to build your language skills, though it does have its limits.
By setting realistic goals, practicing regularly, and using Duolingo as a complementary source for more robust learning methods, you can make significant progress in mastering Korean. With dedication and perseverance, you’ll find yourself navigating conversations and understanding Korean culture with greater ease.
