7 Most Difficult Languages to Learn in the World

One of the hardest languages to learn in the world is Mandarin Chinese, with Arabic and Japanese following just after. But is that all? Well, absolutely no. We have listed the 7 most difficult languages to learn in the world, so when you enrol for these courses, you are prepared for what is coming your way.

A Quick Snapshot: The Most Difficult Languages to Learn in the World

Mandarin-Chinese

Speakers Worldwide: Around 1.1–1.2 billion speakers — making it one of the most spoken languages on Earth.

Speakers in Australia: Mandarin is the most commonly spoken language after English, with about 685,000 people using it at home.

Mandarin is one of the hardest languages to learn because:

• Four main tones (plus a neutral one) that completely change meaning.
• Thousands of characters, each with its own stroke order.
• No alphabet, so memorisation takes time.
• Homophones — many words sound identical, making listening comprehension a challenge.
• Context-heavy grammar, where tiny changes shift the meaning.

Trivia: Mandarin has no alphabet — instead, it uses characters, many of which must be memorised individually!

Arabic

Speakers Worldwide: Around 274 million total speakers when combining native and second-language speakers, and even more if you include dialects spread across North Africa to the Middle East.

Speakers in Australia: About 367,000 people speak Arabic at home, making it one of the top non-English languages spoken in the country.

Arabic is challenging not just because of its script, but because:

• Letters change shape depending on their position in a word.
• Short vowels are often omitted, forcing learners to guess pronunciation.
• Sounds like ‘ح’, ‘ع’, and ‘غ’ don’t exist in most other languages.
• Different dialects vary heavily, so what you learn in class may not match what people speak on the street.
• Verb patterns are complex and require memorisation.

Trivia: Modern Standard Arabic (MSA) is not usually anyone’s first language — it’s used in media and schools, while everyday speech varies wildly by region!

Japanese

Speakers Worldwide: Around 125 million speakers, mostly in Japan.

Speakers in Australia: Japanese isn’t among the top most spoken languages, but some communities speak or learn it, especially through schools and cultural exchange.

Japanese is unique and tough because:

• Three writing systems are used simultaneously (Hiragana, Katakana, Kanji).
• Over 2,000 Kanji characters are required for basic fluency.
• Hierarchical honorifics (Keigo) that change grammar depending on social status.
• Sentence structure (SOV) is very different from English.
• Implied meaning — Japanese often leaves subjects out, requiring you to understand the context deeply.

Trivia: The same word can be written in three different ways (phonetic vs. character), depending on context!

Hungarian

Speakers Worldwide: About 12–13 million speakers, mostly in Hungary and neighbouring countries.

Speakers in Australia: A small Hungarian community exists — roughly 20,000 speakers — but it’s not a major language there.

Hungarian challenges learners for several reasons:

• 18–35 grammatical cases (depending on how you count them).
• Agglutinative structure, meaning long, complex words built from many endings.
• Pronunciation rules that differ greatly from English.
• Unique vocabulary unrelated to Germanic or Romance languages.
• Flexible word order which makes understanding sentences harder for beginners.

Global Trivia Corner: Languages aren’t the only thing that vary across cultures — myths and legends do too. For example, Australian Mythical Creatures like the Bunyip and Yowie.

Finnish

Speakers Worldwide: Around 5–6 million, most in Finland.

Speakers in Australia: Very few — Finnish communities are small and mostly tied to cultural groups.

Finnish is difficult mainly due to:

• 15 grammatical cases that change how nouns behave.
• Vowel harmony, where vowels must match within words.
• Extremely long words formed by combining multiple concepts.
• Minimal resemblance to English, so you can’t guess meanings.
• Conjugation-heavy grammar, especially in verbs.

Korean

Speakers Worldwide: Around 80+ million.

Speakers in Australia: About 115,000 speak Korean at home, making it one of the top 20 languages in the country. 

Korean looks simple early on but becomes tough because:

• Honorific levels change verbs and vocabulary depending on who you’re speaking to.
• Sentence endings carry emotional nuance, intent, and politeness — all different.
• SOV sentence order requires a mental adjustment.
• Particles attached to words can change meaning entirely.
• Pronunciation rules shift depending on what comes before and after.

Russian

Speakers Worldwide: Roughly 255–258 million speakers globally. 

Speakers in Australia: Fewer than Asian languages like Mandarin or Arabic, but Russian communities do exist, especially in some cities.

Russian is difficult for these reasons:

• Six grammatical cases that change word endings.
• Stress patterns are unpredictable — wrong stress can change meaning.
• Verb aspects (perfective vs. imperfective) are tricky to master.
• Consonant clusters (multiple consonants together) make pronunciation tough.
• Cursive Cyrillic looks very different from printed Cyrillic, adding another layer to learn.

Why Should People Learn Hard Languages?

Learning a complex language may seem intimidating at first, but the benefits far outweigh the challenge. Hard languages push you out of your comfort zone, strengthen your brain, and open doors you didn’t even know existed. Whether it’s Mandarin, Arabic, or even Finnish, learning a complex language offers advantages that stay with you for life.

It Sharpens Your Brain

Studies show that learning tough languages improves memory, problem-solving, multitasking, and even creativity. Your brain literally grows new connections as you handle new scripts, sounds, and grammar systems.

It Sets You Apart Professionally

Fluency in a complex language immediately makes your profile stand out. Employers value candidates who put in the effort to master rare or high-demand languages — like Mandarin, Arabic, Korean, or Russian.

It Helps You Understand a Culture Deeply

Language is a doorway to culture. The harder the language, the richer and more unique the cultural insights. From folklore and traditions to humour and daily expressions, you get to experience a world most people never access.

It Builds Patience and Discipline

Hard languages teach you consistency. You learn to embrace slow progress, celebrate small wins, and develop real perseverance — qualities that help you in every area of life.

It Expands Your Global Opportunities

Travel, work, business, studying abroad, or even forming friendships across borders becomes far easier. Tough languages are often spoken in fast-growing regions with significant economic and geopolitical importance.

It Boosts Your Confidence

There’s nothing like the feeling of finally understanding a sentence in a language you once thought was impossible. Every milestone feels like an achievement — and that confidence carries over into other challenges.

It Makes You a Better Communicator

Learning complex grammar, tones, cases, or new writing systems forces you to think deliberately about how you communicate — even in your native language.

Final Thoughts

Learning a difficult language isn’t just about memorising words or mastering tricky grammar — it’s about opening your world. Each challenging language on this list comes with its own script, sounds, culture, and way of thinking. And while the journey may feel intimidating, the rewards are absolutely worth it. You gain a sharper mind, stronger career opportunities, and a deeper connection to people across the globe.

So whether you choose Mandarin, Arabic, Finnish, or any other complex language, remember this: every step you take brings you closer to understanding a new culture, a new perspective, and ultimately, a new version of yourself. The challenge is great — but the transformation is even greater.
