Learning a new language as an adult is entirely possible, but the strategies that work differ from how children acquire language. Research in adult language acquisition points to several highly effective approaches that accelerate progress.

• Use the \comprehensible input\ method: Spend 70% of your study time consuming content you can mostly understand (90%+ comprehension). Watch YouTube videos, TV shows, or listen to podcasts in your target language rather than drilling flashcards.
• Practice speaking early with language exchange apps: Apps like HelloTalk and Tandem connect you with native speakers who want to learn your language. Even 10 minutes of conversation daily dramatically improves fluency.
• Spaced repetition systems (SRS): Use Anki or similar tools for vocabulary retention. Review cards at increasing intervals to move words from short-term to long-term memory efficiently.
• Focus on the most common 1,000 words first: The top 1,000 words in any language cover approximately 80% of everyday conversation. Prioritize frequency lists over obscure vocabulary.
• Establish a daily habit of at least 15 minutes: Consistency beats intensity. A daily 15-minute session is far more effective than cramming for 3 hours once a week.

Verdict: The most effective approach combines comprehensible input (watching/listening to native content) with daily speaking practice and spaced repetition for vocabulary.
