Learning English from Arabic, Chinese, Hindi, or Japanese is one of language learning's greatest challenges. But research reveals exactly what makes it difficult—and the specific strategies that accelerate progress. Here's your evidence-based guide.
You can reach B2 English proficiency in 900-1,200 hours (18-24 months with consistent practice). You'll need to build vocabulary from scratch with <5% recognizable words. Your biggest challenges will be articles, word order, and the Latin alphabet—all completely learnable with the right approach.
Based on FSI and Cambridge research data
English learning timelines depend on "linguistic distance"—how different your native language is from English. Arabic, Chinese, Hindi, and Japanese are among the most distant languages from English, requiring more time but following predictable patterns.
Source: U.S. Foreign Service Institute data and Cambridge English proficiency research tracking learners across 40+ language backgrounds. FSI classifies Arabic, Chinese, and Japanese as Category IV (most difficult for English speakers)—the reverse is equally true.
Unlike European learners who share thousands of words with English, you're building vocabulary almost entirely from scratch. This requires more time but creates a different kind of fluency—one built on deep understanding rather than surface similarity.

Before meaningful language learning begins, you need to become comfortable with the Latin alphabet. This is a real time investment—but once mastered, it applies to dozens of world languages.

Each language background creates specific challenges when learning English. Understanding yours helps you focus practice where it matters most.

Your curve starts slower due to script transition and vocabulary building, but accelerates as foundational skills solidify. The middle months often feel fastest as patterns click into place.

Research consistently shows adults have significant cognitive advantages over children when learning languages. You can use strategies, recognize patterns, and apply knowledge transfer that children simply cannot access.

Research shows intrinsic motivation (internal desire to learn) dramatically outperforms extrinsic motivation (external rewards/pressure) for language acquisition. The difference affects both persistence and ultimate achievement.

Frequency matters more than session length. Research shows 3-5 days per week optimizes memory consolidation and prevents burnout. Use this tool to see how different schedules affect your progress.

Making mistakes isn't just acceptable—it's essential. Research shows errors trigger deeper cognitive processing that passive exposure cannot replicate. The key is making errors in low-stakes practice environments.

100 hours of study over 3 months produces dramatically better results than 100 hours spread over 12 months. Compression creates momentum, maintains context, and prevents the decay that happens between sporadic sessions.

Language learning physically changes your brain. Neuroimaging studies show measurable structural changes within months of beginning intensive study. These changes persist and create cognitive benefits beyond language.

The largest study ever conducted on language learning ability (669,498 participants) found that while children have advantages in some areas, adults retain strong language learning capacity well into adulthood.
Key Finding: Grammar learning ability remains strong until ages 17-18, then declines gradually—but never to zero. More importantly, thousands of adults in the study achieved native-range proficiency when they started after age 20. The "critical period" affects the probability of reaching native-like proficiency, not the ability to become fluent.
