Why These 10 Roots Matter

These 10 roots alone can help you understand over 500 common English words. When you encounter an unfamiliar word, try breaking it apart:

1. Find the root — What's the core meaning?
2. Check the prefix — How is the meaning modified?
3. Look at the suffix — What part of speech is it?

This three-step process turns vocabulary learning from memorization into understanding. And understanding sticks far longer than rote memory.
