English is considered a moderately difficult language to learn, and where it lands depends entirely on which part of English you mean. Its grammar is genuinely simple compared to most world languages, with no noun genders, minimal verb conjugation, and a fairly forgiving word order. Its spelling and pronunciation are a different story, full of exceptions that trip up even confident learners. According to Cambridge English's guided learning hours, most students reach a solid conversational level on the Common European Framework (CEFR B1) after roughly 350 to 400 hours of study, though real fluency takes considerably longer.
Short answer: English grammar is relatively easy, with no grammatical gender and simple verb conjugation, but its spelling and pronunciation are among the most irregular of any major language. Most learners reach conversational level (B1) in 350 to 400 guided hours; full fluency (C2) can take 1,000 hours or more. Difficulty also depends heavily on your own native language.
This is the myth that gets repeated the most, usually by people comparing English favourably to languages with grammatical gender or complicated case systems. And it's not wrong, exactly. It's just incomplete.
Compared to German, which sorts every noun into der, die or das, or Russian, which changes noun endings across six different cases, English really is lighter going. Nouns don't have gender. Adjectives don't change form to match them. Verbs barely conjugate at all: "I walk," "you walk," "we walk," and only "he walks" breaks the pattern. Articles are limited to "a," "an" and "the," full stop.
So the grammar claim holds up. But grammar is only one layer of a language, and English makes up for its simple grammar in other places, which is where most of the real difficulty actually lives.
In languages like Spanish, Italian or Korean, spelling maps closely onto sound. Learn the rules once and you can read almost anything aloud, even words you've never seen before. English offers no such guarantee.
Take "through," "though," "tough," "thought," "cough" and "bough." All six end in the same four letters. None of them rhyme with each other. "Read" is pronounced differently depending on whether you mean the present or the past tense, and the only way to know which is context. There isn't a consistent rule hiding underneath any of this that a learner can simply apply.
The reason comes down to history rather than logic. English vocabulary was pulled in from Old English, Norman French, Latin, Greek and dozens of other sources over more than a thousand years, and each wave of borrowing brought its own spelling habits along with it. Printing then locked many spellings in place before English pronunciation had finished a major sound change known as the Great Vowel Shift, so the written and spoken language drifted apart and never really reconciled.
Learners sometimes assume that because English skips gendered nouns, there's less to memorise overall. That's not really true, it's just a different kind of memorisation.
Irregular verbs have to be learned one at a time, since there's no reliable pattern connecting "go" to "went" to "gone," or "is" to "was" to "been." Irregular plurals do the same thing: "mouse" becomes "mice," "child" becomes "children," and "sheep" doesn't change at all. None of this can be worked out from a rule, only from repetition.
Phrasal verbs deserve special mention here, since they're often what separates a confident intermediate speaker from someone who still sounds like they're translating in their head. "Look up" a word in a dictionary, "look up to" someone you admire, or just "look up" at the sky: three completely different meanings from the same two words, and no shortcut except hearing and using each one enough times that it sticks.
How hard English feels depends enormously on what language you already speak. This gets left out of a lot of "is English hard" discussions, which tend to talk about the language in isolation rather than relative to a learner's starting point.
If your first language is Dutch, German or one of the Scandinavian languages, you already share a huge amount of underlying grammar and vocabulary with English, since they all descend from the same Germanic branch. Speakers of French, Spanish, Italian and other Romance languages get a different kind of head start, since roughly a third of English vocabulary was borrowed from Norman French and Latin, so thousands of longer English words already look and mean roughly what they expect.
For speakers of Japanese, Arabic, Mandarin or Korean, English tends to be a genuinely harder climb. There's often no shared vocabulary to lean on, the sentence structure and sound system can be very different, and if the native script isn't Latin-based, reading itself becomes an extra hurdle before the language even starts. It's the same logic in reverse that the US Foreign Service Institute uses when it rates Japanese, Arabic, Mandarin and Korean as the hardest languages for English speakers to learn.

Cambridge English publishes guided learning hours for each CEFR level, based on data from students working with a teacher in a classroom setting. These numbers are cumulative, meaning they represent total hours from zero, not extra hours on top of the previous level:
Those figures assume a classroom with a teacher. Self-study and immersion change the maths considerably, in both directions. A structured immersion environment, where you're hearing and using the language for hours every day, tends to compress these timelines a lot. A casual learner doing thirty minutes a day on their own, by contrast, will usually take longer in calendar time to hit the same hour totals, even though the total hours needed stay roughly the same.
Put in practical terms, someone studying half an hour a day, most days, tends to reach a comfortable B1 conversational level within about two years. That's not a discouraging number. It just means fluency is a hobby-length project, not a weekend one, and building a strong core vocabulary early tends to pay off more than trying to memorise grammar tables. Vocabulary-first tools, including games like our language learning game, are built around exactly that idea, anchoring new words to real objects and situations rather than isolated lists.
Reaching C1 or C2 feels like an obvious finish line, and in a practical sense it is: at that point you can work, study and socialise in English without much friction. But it isn't the end of learning, because English never really stops adding new material.
Estimates of total English vocabulary run past 600,000 words once you count technical and historical terms, and that number keeps growing every year as slang, internet culture and new industries add fresh words and phrases. Even confident native speakers regularly hear words they don't recognise, whether that's a regional idiom, a piece of internet slang, or specialist vocabulary from a field they don't work in.
The good news for learners is that fluency was never about knowing every word. It's about knowing enough of the common ones to communicate confidently and pick up the rest naturally as you go, the same way native speakers do. That's a far more achievable target than it sounds, and it's exactly why the earliest hours of study, spent on the vocabulary that shows up constantly rather than the vocabulary that shows up rarely, matter more than any other stage.

Spelling and pronunciation are much harder, full of exceptions that don't follow the written rules. Overall, most linguists rate English as moderate difficulty, and your actual experience depends heavily on your native language.
Using Cambridge English's guided learning hours, reaching conversational fluency (CEFR B1) takes roughly 350 to 400 hours of study. Professional fluency (C1) takes around 700 to 800 hours, and near-native mastery (C2) can take 1,000 hours or more.
English vocabulary was borrowed from Old English, Norman French, Latin, Greek and dozens of other languages over more than a thousand years, and each wave brought its own spelling habits. Printing also standardised many spellings before English pronunciation had finished shifting, which is why written and spoken English drifted apart.
Most learners find phrasal verbs and irregular verbs the hardest part, not sentence structure. Phrasal verbs like "give up," "look into" and "run out of" have meanings that often have little to do with either individual word, and there's no shortcut except learning them one at a time.
For a native English speaker, French and Spanish are both rated Category I by the US Foreign Service Institute, the easiest group. For a non-native speaker learning English, difficulty depends on their own native language. Speakers of Germanic or Romance languages tend to find English more approachable than speakers of languages with no shared vocabulary or grammar, such as Japanese or Arabic.
No. Native speakers regularly break formal grammar rules in casual speech, use contractions, and mix up rules like "who" versus "whom" without anyone noticing. Learners often hold themselves to a stricter standard than native speakers apply to themselves.
Learning high-frequency words first, in context rather than as isolated lists, tends to work best. Around 3,000 word families cover roughly 95 percent of everyday conversation, so focusing there before branching into specialised vocabulary gives the fastest practical return.
Both groups have real advantages, just different ones. German speakers share English's Germanic grammar backbone and many everyday cognates like "house" and "Haus." Spanish speakers benefit from thousands of Latin-derived words that overlap with English, especially in longer, more formal vocabulary.
Around 3,000 word families gets you to comfortable conversational fluency, since that covers most everyday speech. Reaching a near-native level typically means recognising 8,000 to 10,000 word families, though few people, including native speakers, actively use that many.
Yes, particularly for building the core vocabulary that makes up most everyday conversation. Games that pair words with native speaker audio and real-world context, and bring learners back to review words on a spaced schedule, tend to build retention faster than flashcard lists alone.
