I spent a month with Assimil Khmer. Here’s my honest take.
The book was written decades ago. You will learn how to say “The postman is arriving,” but you won’t learn “WiFi” or “Smartphone” until the appendix. The cultural references are a bit... French colonial nostalgia. assimil khmer
Most courses teach you textbook phrases like, “The pen is on the table.” Assimil teaches you things like, “ញ៉ាំបាយហើយឬនៅ?” (Have you eaten rice yet?)—which is literally how Cambodians say “How are you?” I spent a month with Assimil Khmer
Assimil Khmer is the best tool for the intermediate beginner. It fails as a true "zero to hero" course because of the script difficulty. However, once you learn how to read (even slowly), this book is a goldmine. this book is a goldmine.
