A clear framework for learners who want to stop guessing and start progressing.

Most language learners stall in their learning progress, and it’s for the same reason: they follow advice without understanding the underlying principles.

This book is a complement to the foundational knowledge you have learnt in The Language Learner’s Handbook. The Principles of Language Learning will explain the 24 core ideas that underly all effective language learning techniques. With them you will be able to evaluate methods for yourself, avoid dead ends, and make confident decisions about how you study to become a highly successful language learner.

You already know how to start, now learn how to think.
