Is English Hard to Learn? Difficulty Ranked Against 20 Other Languages

Roughly 1.5 billion people are learning English right now — yet surveys consistently show that learners abandon the language more often than almost any other. So is English actually hard to learn, or does it just have a reputation problem? The honest answer depends almost entirely on where you are starting from. Your native language, the writing system you grew up with, and the grammar structures already wired into your brain all shape how steep the climb really is.

What Is English Language Difficulty — and How Do We Measure It?

Language difficulty is the estimated time a typical adult learner needs to reach professional working proficiency in a new language, starting from zero.

The most widely cited benchmark is the US Foreign Service Institute (FSI) classification system. The FSI trains American diplomats and has tracked learning hours for over 70 languages since the 1970s. It groups languages into four categories based on how long they take an English native speaker to reach professional proficiency (roughly equivalent to CEFR C1).

This gives us a concrete, evidence-based starting point — even though it measures difficulty from English, not to English. The principle of linguistic distance works both ways: languages that are far from English for an American diplomat are also languages whose speakers find English most challenging.

The FSI Difficulty Tiers: Where Does English Sit?

The FSI does not formally rate "English for non-native speakers", but by applying the same logic in reverse — measuring structural distance from a learner's mother tongue — researchers and applied linguists have produced reliable estimates. Here is how English compares against 20 other languages.

Where English Ranks for Non-Native Speakers

Applying FSI logic in reverse, English sits at Category I–II difficulty for most European learners, and at roughly Category III difficulty for speakers of Arabic, Chinese, Japanese, and Korean. The asymmetry is real: a Spanish speaker can reach B2 English in roughly 600 hours, while a Japanese speaker typically needs 900–1,100 hours.

Crucially, English is not the hardest language to learn — that title belongs to Mandarin, Arabic, and Japanese regardless of the direction of travel.

The pattern is clear: the greater the structural gap between English and your mother tongue, the harder English becomes for you.

What Makes English Hard to Learn?

English has several genuinely difficult features that trip up learners at every level. Understanding them makes them easier to tackle.

1. Spelling and Pronunciation

English spelling is arguably its most notorious trap. The language absorbed vocabulary from Latin, Old French, Norse, and Greek without regularising pronunciation. The result: "though", "through", "tough", "cough", and "hiccough" all end in "ough" but produce five different sounds.

Research suggests only around 400 of the 1,100 most-used English words follow consistent phonetic rules. This is far lower than Spanish (near-perfect phonetic consistency) or German (highly predictable once rules are learnt).

2. Phrasal Verbs

Phrasal verbs — verbs combined with prepositions or adverbs to create new meanings — are one of English's most opaque systems. "Give up", "give in", "give out", "give away", and "give off" share the same base verb but mean entirely different things, with no logical pattern a learner can reliably predict. Oxford's English dictionary lists over 5,000 phrasal verbs in common use.

3. Articles (a, an, the)

The definite article "the" and indefinite articles "a/an" follow rules that are surprisingly complex. Learners whose native languages have no articles — including Russian, Polish, Japanese, Arabic, and Mandarin — consistently identify articles as one of the last features to become automatic. The difference between "I saw a doctor" and "I saw the doctor" changes meaning fundamentally, yet the rule is contextual and subtle.

4. Irregular Verbs and Tenses

English has twelve tense forms in active voice alone. While many languages use tense, aspect, and modality, English combines all three in a single verb phrase ("she had been working" = past perfect progressive). Irregular verbs — "go/went", "buy/bought", "think/thought" — must largely be memorised, as they follow no productive pattern. There are over 200 common irregular verbs in English.

5. Stress and Intonation

English is a stress-timed language, meaning syllable length varies in a way that carries meaning. "REcord" (noun) and "reCORD" (verb) are the same letters but different words, distinguished only by stress. This is particularly difficult for speakers of syllable-timed languages such as Spanish, French, Italian, and Mandarin.

What Makes English Easier Than You Might Expect

Before you feel overwhelmed, it is worth noting why English consistently attracts more learners than any other language on earth — and keeps them.

• No grammatical gender. Unlike French, Spanish, German, or Russian, English nouns carry no gender. "Table", "book", "city" — all genderless. There are no adjective agreements to memorise.
• Relatively simple case system. Modern English has almost entirely abandoned its Old English case system. You do not need to change word endings depending on grammatical role, unlike Russian (six cases), German (four cases), or Finnish (fifteen cases).
• Consistent word order. English uses Subject–Verb–Object order reliably (I eat apples). This logical structure is predictable and easier to internalise than verb-final languages (Japanese, Korean) or languages with free word order.
• Global exposure. English is everywhere: films, music, social media, games, business. This ambient input dramatically accelerates acquisition compared with minority languages where learners must create practice opportunities artificially.
• No tonal system. Unlike Mandarin (4 tones), Cantonese (6–9 tones), or Vietnamese (6 tones), English does not use pitch to distinguish word meaning, which removes an entire learning dimension.

How Your Native Language Affects English Difficulty

The concept of linguistic distance — how structurally different two languages are — is the single most reliable predictor of learning difficulty. Here is a practical breakdown by language family.

Romance Language Speakers (Spanish, French, Italian, Portuguese)

Learners from Romance language backgrounds benefit from shared vocabulary, a familiar Latin alphabet, and similar sentence structures. The main hurdles are articles (absent in Latin), phrasal verbs, and English's inconsistent spelling. Expected time to B2: 450–600 hours of guided study.

Germanic Language Speakers (German, Dutch, Swedish, Norwegian)

Germanic learners share the closest family relationship with English. Vocabulary overlap is high, and both subject-verb-object order and the concept of articles exist in their native languages. Expected time to B2: 400–550 hours.

Slavic Language Speakers (Russian, Polish, Czech)

Slavic learners face the article challenge acutely, since Slavic languages have no articles. Verb aspects (perfective/imperfective) map imperfectly onto English's tense system. Expected time to B2: 650–800 hours.

Arabic, Chinese, Japanese, Korean Speakers

These learners face the largest structural gap: different scripts (requiring learners to acquire a new writing system alongside grammar), absent articles, and fundamentally different sentence structures. Expected time to B2: 800–1,100 hours.

Common Mistakes English Learners Make (and How to Fix Them)

• Translating literally from your native language. English idioms and phrasal verbs rarely translate word-for-word. Fix: learn phrases as chunks, not individual words — "I look forward to hearing from you" is one unit, not five separate vocabulary items.
• Ignoring pronunciation early on. Learners who focus only on grammar and reading often develop fossilised pronunciation errors that are hard to correct later. Fix: include listening and speaking practice from lesson one, even at A1 level.
• Over-relying on a single input type. Reading textbooks alone will not teach you informal spoken English. Fix: diversify — podcasts, films, conversation exchanges, and written production all train different sub-skills.
• Avoiding the article system. Many learners omit articles entirely under time pressure, assuming context will carry meaning. Fix: study article rules explicitly with a grammar reference, then practise in writing where you have time to self-correct.
• Not tracking progress against a framework. Without a benchmark, learners often do not know which level they have reached or what the next milestone looks like. Fix: use a recognised framework. Our overview of English for levels explains exactly what competencies each CEFR level requires.

How Long Does It Take to Reach Each CEFR Level?

The Common European Framework of Reference (CEFR) provides the globally accepted benchmark for English proficiency. Here are standard guided learning hour estimates for a Romance-language adult learner.

These figures increase by 30–50% for Arabic, Chinese, Japanese, and Korean native speakers.

Conclusion

English is neither the easiest nor the hardest language to learn — it sits firmly in the middle tier globally. Its difficulty is highly personal: a Spanish or Italian speaker will find it significantly more accessible than a Mandarin or Arabic speaker, who faces a structural gap measured in hundreds of additional study hours.

Key takeaways:

• FSI data places English at Category I–II difficulty for European learners and Category III for East Asian and Arabic speakers.
• English's hard side: irregular spelling, phrasal verbs, the article system, and stress-timed pronunciation.
• English's easy side: no grammatical gender, minimal case endings, logical word order, no tonal system, and massive global exposure.
• CEFR hours to B2 range from ~500 hours (Romance speakers) to ~1,100 hours (Arabic/Chinese/Japanese speakers).
• Knowing your current level is the most efficient first step — it removes guesswork and focuses your study.
