Does Duolingo Teach Spelling? What It Does and What to Add

You have a long streak. You can order food, describe your weekend and follow a short story in English. Then you write a real email to a colleague or a teacher and stop in the middle of "receive", unsure whether the e or the i comes first, and you wonder whether all those lessons were teaching you to spell at all.

The fair answer is: partly. Duolingo exposes you to thousands of written English words and asks you to type many of them, and that does build some spelling knowledge. But it was designed to teach a language, not to teach spelling, and several things about the way it works make it easy to finish a lesson without ever producing a hard word from memory.

This guide explains what Duolingo does and does not do for your spelling, and compares the tools that fill the gap, with prices checked on each company's own site or app store listing in late September and early October 2026. We make one of those tools, and it appears in the comparison as one option among several, with its limits.

What Duolingo is good at

Duolingo offers English courses for speakers of many other languages, and its English course is one of those aligned to the CEFR, the common European scale that runs from beginner (A1) to advanced (C2). Lessons mix reading, listening, speaking and writing in short sessions, and the streaks, reminders and small rewards are very good at one thing that matters enormously: getting you to practice every day.

That habit is not trivial. Many people fail at language learning because they stop, not because they choose the wrong method. If Duolingo keeps you showing up, it is doing real work.

It also uses spaced repetition, the idea that material should come back just as you are about to forget it. In 2016, Burr Settles and Brendan Meeder of Duolingo published a paper describing a model the company built to estimate how quickly each learner forgets each word and to schedule practice accordingly. The idea is sound, and it is the same principle that good spelling tools use.

Where spelling slips through

The trouble is what you actually do in many exercises.

Much of Duolingo lets you build answers by tapping word tiles from a word bank. That is recognition: the correct spelling is on the screen, and you only have to pick it. Recognition is much easier than producing a word from memory, and it teaches much less. Henry Roediger and Jeffrey Karpicke's 2006 study of the testing effect, among many others, showed that recalling something strengthens it far more than seeing it again.

When you do type, the course is focused on whether you understood and produced the right sentence. Learners have long reported that Duolingo sometimes accepts an answer containing a small slip and points out the typo, rather than marking it wrong. That is a kind design for a language course, because it keeps you moving. For spelling, it means a near-miss can feel like a success.

And Duolingo does not teach spelling patterns. It will not explain why "hoping" has one p and "hopping" has two, or why "necessary" has one c and two s's. Linnea Ehri's research on orthographic mapping, the process by which a word's sounds become bonded to its letters in memory, suggests those explanations matter: words stick when you understand how their letters represent their sounds and meaning, not when you have simply seen them many times.

So, does Duolingo teach spelling?

It teaches common words reasonably well through repeated exposure, especially if you choose to type rather than tap. It does not teach the rules and patterns of English spelling, it does not force you to produce difficult words letter by letter, and it is not organized around the specific words you personally misspell.

For a beginner, that is fine. At A1 and A2, the words are short and regular, and exposure does most of the work. From about B1 upward, where words like "accommodation", "environment" and "occurred" start to appear in your writing, most learners need something more focused.

One more point, because people search for it. Duolingo does not offer an English course for native English speakers, so it is not a spelling course for them. Its separate app for young children, Duolingo ABC, teaches letters, sounds and early reading, and it is free with no ads.

Signs Duolingo is not enough for your spelling

You do not need a test to know whether your spelling needs more help. Your own writing will tell you, if you look at it honestly for a week.

The clearest sign is repetition. If a spell-checker flags the same handful of words in your emails again and again, such as "recieve", "goverment" or "begining", those words have never been stored correctly, and more exposure will not store them. Another sign is hesitation: you know the word, you use it every day, and you still stop before typing it. That pause is your memory telling you that it holds two versions and is not sure which is right.

A third sign is a goal where spelling is scored. In IELTS Listening, a misspelled answer earns no mark, and the TOEFL now includes a reading task in which you complete the missing letters of words. If either exam is in your plans, spelling has moved from a nice extra to a requirement.

None of this means you should stop Duolingo. It means Duolingo has done what it does well, and the next step needs a different kind of practice.

What to use alongside it

A focused dictation tool

The most direct complement to Duolingo is a tool that does the one thing Duolingo does least: says a word and makes you spell it, with no tiles and no forgiveness for a missing letter.

Ours works that way. A recorded American English voice says the word, you type it and press Enter, and you see exactly which letters went wrong and why, along with the meaning and an example sentence. FSRS, an open-source spaced-repetition algorithm, schedules each word for review at growing intervals. There are ten levels, a short warm-up that finds yours, and extra practice on any pattern you keep missing, such as double letters or the -tion ending. British spellings are accepted. Its limits: it teaches spelling only, the voice is American, and after the first 14 days the free plan adds three new words a day.

Anki does the same job for free if you are willing to build it. You create cards with audio and a box to type into, and it checks your answer letter by letter and schedules reviews very well. It suits a learner who wants full control over a personal word list. Spelling Notebook, a small iPhone app, is the simplest version: type in your own list, and it reads each word aloud for you to spell. The free version takes eight words per list; the $1.99 Premium version removes the limit and offers British, American and Australian voices.

Rules and meaning: Spellzone, Vocabulary.com and a good dictionary

If you want to understand English spelling rather than only practice it, Spellzone is a UK-built course that covers both British and American spelling in 36 units, from basic patterns to the rule-breakers. Its word lists can be translated into 92 languages, which helps if you want to check a meaning in your first language. It costs $39 a year after a 7-day trial.

Vocabulary.com suits upper-intermediate learners who want vocabulary and spelling together. Its Spelling Bee activity shows a definition, plays the word, and asks you to type it. A free account allows 10 trainer questions a day.

And keep a dictionary with audio open. Merriam-Webster.com is free, and hearing a word said while you look at its spelling is a small, reliable habit that builds the sound-to-letter links Ehri describes.

A checker, used the right way

Grammarly and similar checkers are good at catching spelling mistakes in your real writing, and the free plan covers basic spelling. They do not teach you, because they fix the word before you have tried to recall it. Use one the other way around: write first, then check, and copy every flagged word onto your practice list. Our article on why spell-check can make your spelling worse explains the risk.

How to combine them in a few minutes a day

You do not need to give up Duolingo. Keep your streak, and add a short spelling routine next to it.

First, change how you use Duolingo. Where an exercise offers a keyboard instead of word tiles, choose the keyboard. When Duolingo flags a typo in an answer it accepted, treat it as a mistake and write the word down.

Second, keep a personal list. Every word you hesitate over in Duolingo, in an email or in a chat message goes on it. Your own mistakes are worth more than any ready-made list, especially the words your first language makes hard: Spanish speakers often struggle with double consonants, for example, and Arabic speakers with vowels. Our guide to English spelling for ESL learners covers the most common traps by language.

Third, practice that list for a few minutes a day, from memory, with spaced review: words you miss come back tomorrow, words you get right come back in a few days, then a week. A 2022 meta-analysis by Su Kyung Kim and Stuart Webb found that spaced practice gives second-language learners a clear advantage over massed practice, so the schedule is not a detail. It is most of the benefit.

What to do next

After your next Duolingo lesson, write down three words you were not completely sure how to spell. Practice them from memory tomorrow and again in three days. If that habit sticks, add a dictation tool from the table above to run the schedule for you. If you are preparing for an exam, our guide to Duolingo English Test spelling explains how that test treats misspellings.

To try listen-and-type practice with spaced review, you can spell five words on Spelling.School's home page with no sign-up. For a wider comparison, see our review of spelling apps for ESL learners.

Questions people ask

Does Duolingo improve spelling?

Duolingo improves spelling of common words through repeated reading and some typing, especially if you choose to type answers rather than tap word tiles. It does not teach spelling rules or patterns, and learners report that it sometimes accepts answers with small typos. Most learners from intermediate level upward need a focused spelling tool alongside it for longer and harder words.

Is Duolingo enough to learn English?

Duolingo is a good way to build a daily habit and learn basic vocabulary and grammar, and it can take a beginner a long way. Most learners who need English for study, work or an exam also need more extended reading, writing, speaking with real people, and focused practice on weak areas such as spelling. Think of it as one part of your learning rather than all of it.

Does Duolingo accept spelling mistakes?

Learners have long reported that Duolingo sometimes accepts a typed answer with a small slip and points out the typo instead of marking it wrong. This keeps lessons moving, which suits a language course. For spelling practice, treat every flagged typo as a mistake and add the word to your own practice list.

What is the best app to use with Duolingo for spelling?

The best partner is a tool that says a word aloud, makes you type it from memory, and brings missed words back over several days, because that is what Duolingo does least. Anki can do this for free with your own word list, and dedicated dictation apps run the schedule for you. A free dictionary with audio, such as Merriam-Webster.com, is also worth keeping open.

Does Duolingo have an English course for native speakers?

No. Duolingo's English courses are for speakers of other languages. For young children learning to read in English, the separate Duolingo ABC app teaches letters, sounds and early reading, and it is free with no ads. Native speakers who want to improve their spelling need a dedicated spelling tool or course.

How can I practice English spelling every day?

Keep a personal list of words you misspell or hesitate over, and spend a few minutes a day spelling them from memory after hearing them. Check each answer straight away and note exactly which letters went wrong. Bring missed words back the next day and correct ones a few days later, then a week later, so that the gaps between reviews keep growing.
