For a native English speaker, the short answer is Spanish, Italian, Portuguese, Dutch, Norwegian and Swedish, with French close behind. That is not a matter of taste: the US Foreign Service Institute, which teaches languages to diplomats full time, puts exactly these in its fastest group. But "easiest" always means easiest from somewhere. A Spaniard gets Portuguese almost free, and a Japanese speaker finds Korean grammar strangely familiar. This piece is written for a reader whose first language is English, and it ends with the question that matters more than the ranking.
Key points
- The FSI sorts languages into four categories for English speakers, from about 24–30 weeks of full-time study for the closest to about 88 weeks for the furthest.
- Five things make a language easy: the script, shared roots, the grammar, the sounds, and how much material exists at your level.
- An easy language you have no use for is harder to keep than a hard one you need. Easy saves months; it does not supply a reason.
Five things that make a language easy
1. The script. With a Latin alphabet you can read a menu on day one. A new alphabet costs weeks, not years: Cyrillic or Korean hangul take days to a couple of weeks. A writing system with thousands of characters, like Japanese kanji, is a project that runs alongside the whole course.
2. Shared roots. English borrowed so heavily from French and Latin that every Romance language hands you thousands of words before you open a book: information, información, informazione, informação. The Germanic languages give you the everyday core instead: Dutch water, huis, boek; German Wasser, Haus, Buch.
3. The grammar. What costs time is grammar with categories English does not have. No cases and no grammatical gender is a gift; regular verbs are another. Norwegian and Swedish are a pleasant surprise here: the verb does not change for the person at all, so Norwegian jeg er, du er, han er is "I am, you are, he is" with one form.
4. Sounds and spelling. Spanish and Italian are written roughly as they are pronounced, so a word you read is a word you can say. French and Danish are the reverse: friendly on paper, hard on the ear.
5. Material at your level. Series, podcasts, graded readers, songs, people to practise with. This is where Spanish wins outright, and it is why an "easy" language with few resources can feel harder than its category suggests.
The ranking
The categories are the FSI's; the notes on what helps and what hurts are ours.
| Language | FSI category | Script | What helps | What will still be hard |
|---|---|---|---|---|
| Spanish | I | Latin | Spelling follows sound, endless material, many shared roots | Two past tenses, the subjunctive, fast speech |
| Italian | I | Latin | Spelling follows sound, Latin vocabulary | Double consonants, prepositions fused with articles |
| Portuguese | I | Latin | Latin vocabulary, regular spelling | Nasal vowels, Brazil and Portugal sound very different |
| Dutch | I | Latin | A Germanic core close to English | Word order, the throaty g |
| Norwegian, Swedish | I | Latin | Verbs do not change for the person | Pitch accent, the article glued to the end of the noun |
| Danish | I | Latin | Grammar as simple as Norwegian | Pronunciation that swallows consonants |
| French | I | Latin | Huge shared vocabulary | Listening: spelling and sound part ways |
| Romanian | I | Latin | Romance vocabulary | Cases, the article at the end of the noun |
| German | II | Latin | Everyday cognates, spelling follows sound | Four cases, three genders, the verb at the end |
| Indonesian | II | Latin | No conjugation, no gender, no tenses to inflect | Vocabulary with no shared roots, affixes |
| Russian, Vietnamese | III | Cyrillic, Latin with tone marks | Cyrillic takes a week; Vietnamese has no conjugation | Six cases and verb aspect; six tones |
| Japanese, Korean | IV | Kana and kanji, hangul | Hangul in a few evenings, regular grammar | Honorifics, word order, kanji |
Category I means roughly 24–30 weeks of full-time classes to professional working proficiency, Category II about 36, Category III about 44 and Category IV about 88. The full list and the method are on the FSI's page on language training.
Two honest notes on the table
The weeks are not your weeks. They describe diplomats in class for hours every day with a teacher, not an adult with a job and twenty minutes on the train. Use them as ratios: Japanese takes about three times as long as Spanish, not "88 weeks". The arithmetic for a normal life is in how long it takes to learn a language.
Easy languages are easy at the start. Spanish gives you a working sentence in week one and the subjunctive at B1, and that is where many learners stall. Korean is the reverse: hangul is a weekend's work and the grammar is regular, but the distance from English shows up in every sentence for years. Neither is a reason to pick or avoid; it is a reason to expect the hard part where it actually is.
What if your goal is not the easiest language, but the one you need
Most people who search for the easiest language already have a candidate they are quietly afraid of: their partner's Korean, the Russian of their in-laws, the German of a job offer. If that is you, the ranking above answers the wrong question. A Category IV language you have a daily reason to use beats a Category I language you picked for its category, because the reason is what carries you through month three. How to weigh desire, use and difficulty against each other is the subject of which language should you learn.
And "hard" is mostly two separate costs that you can pay one at a time. The script comes first and is smaller than it looks: the hangul chart fits on one screen. The grammar comes after and is simply a longer road, not a closed one.
A one-week test to find your own easy language
Lists rank languages; you are one person with one ear and one memory. Before committing, give two candidates three short sessions each:
- Read a short paragraph aloud and check how much of it you got right.
- Listen to two minutes of slow, clear speech and count the words you caught.
- Learn twenty everyday words, then test yourself two days later.
The language that leaves more behind after the third session is easy for you, whatever its category.
In LinguaPair
All ten languages here are full courses from A0 to C2, including the Category I and II languages from the table: Spanish, Italian, Portuguese, French and German. A0 and A1 are free in every course, so the one-week test above costs nothing, and every course starts with its writing system, so a new alphabet is the first level rather than an obstacle. If you learned a language at school, the free level test puts you on the right lesson instead of the first one. And if your "needed" language is your partner's, the app is built for learning it together.
