10 hardest languages for English speakers to learn

Learning a new language can create opportunities for travel, business and cultural exchange, but some languages require significantly more time for English speakers to master than others.

According to language-learning organisations, such as Effective Language Learning and Rosetta Stone, languages are ranked based on the amount of study typically needed to reach professional working proficiency. The ranking, which draws on Foreign Service Institute-style benchmarks, shows that the level of difficulty largely depends on how different a language is from English.

Category III languages present challenges such as unfamiliar grammar structures, pronunciation patterns and writing systems. Category IV languages, classified as “super-hard,” combine several of these obstacles, making them among the most demanding for English speakers.

Experts note that learning tonal systems, new alphabets or thousands of written characters can significantly increase study time. Despite these challenges, millions of learners successfully achieve fluency through consistent practice and long-term commitment.

According to the estimates, learners may need up to 88 weeks of study to achieve proficiency in the most difficult languages.

Here are the 10 hardest languages for English speakers to learn.

1. Arabic – 88 Weeks
Arabic is one of the most widely spoken languages in the world, with speakers across the Middle East and North Africa.

The language uses its own script, which differs completely from the Latin alphabet used in English. Learners must also adapt to reading and writing from right to left.

Arabic includes a range of regional dialects, meaning that spoken language can vary significantly between countries. These factors contribute to its placement in Category IV.

2. Cantonese Chinese – 88 Weeks
Cantonese is spoken mainly in Hong Kong, Macau and parts of southern China.

One of the main challenges for English speakers is its tonal system. The meaning of a word can change depending on the tone used when speaking.

Learners must also become familiar with Chinese characters, which require memorisation rather than alphabet-based spelling.

3. Mandarin Chinese – 88 Weeks
Mandarin is the world’s most spoken native language and serves as the official language of China and Taiwan.

Like Cantonese, Mandarin relies on tones to convey meaning. A slight change in pronunciation can result in a completely different word.

The writing system uses thousands of characters, creating an additional challenge for learners accustomed to alphabet-based languages.

4. Japanese – 88 Weeks
Japanese combines several language-learning challenges into one system.

The language uses three writing systems: Hiragana, Katakana and Kanji. Learners must understand all three to read and write effectively.

Sentence structure also differs from English, requiring learners to think about grammar in a different way.

5. Korean – 88 Weeks
Korean completes the Category IV group of “Super-Hard” languages.

Although it uses Hangul, a unique alphabet designed specifically for the Korean language, learners still face significant grammatical differences compared with English.

The language structure, sentence patterns and levels of formality require substantial study before proficiency can be achieved.

6. Urdu – 44 Weeks
Urdu is spoken by millions of people in Pakistan and India.

It belongs to Category III and requires around 44 weeks of study.

The language uses a script derived from Persian and Arabic, which means learners must master a new writing system alongside unfamiliar vocabulary and grammar patterns.

7. Uzbek – 44 Weeks
Uzbek is the official language of Uzbekistan and is spoken across Central Asia.

The language introduces grammatical structures that differ considerably from English. Word formation and sentence construction often require learners to adopt new language habits.

These differences place it among the more difficult languages for English speakers.

8. Vietnamese – 44 Weeks
Vietnamese presents a challenge largely because of its tonal nature.

Words can carry different meanings depending on how they are pronounced, making listening and speaking particularly demanding for English speakers.

Although it uses a Latin-based script, mastering tones remains a significant hurdle.

9. Xhosa – 44 Weeks
Xhosa is one of South Africa’s official languages and is known for its click consonants.

These sounds are uncommon in English and require learners to develop new pronunciation skills.

The language’s grammatical structure also differs from English, adding to the learning process.

10. Zulu – 44 Weeks
Another major language spoken in South Africa, Zulu, shares some similarities with Xhosa, including the use of click sounds.

Learners must also understand noun classes and grammatical rules that have no direct equivalent in English.

As a result, Zulu remains among the most time-intensive languages in Category III.
