A personified yak English teacher that teaches most common English words by level A1 to C1 for beginners.

Most Common English Words By Level

A1 → C1 vocabulary you’ll actually use in real life (with meanings + sentences).

“By level” usually means CEFR levels (A1 beginner → C1 advanced). These lists aren’t magic—frequency changes by topic—but this is a solid, real-world set of high-utility words to learn in order.

Pro tip: Don’t just memorize. Learn the word, then steal the sentence pattern. Your brain likes patterns. Your brain is also lazy. We work with that.
