You may not realize it, but you already know enough to help your vocabulary grow exponentially. English is a language based on Latin, Greek and Germanic prefixes, suffixes and roots. If you understand the meaning of these word parts and how they fit together, you have the tools to understand hundreds of thousands of other words. I didn’t invent this approach, but I have expanded the prefix and root list considerably, and added a unique visual learning component which could be helpful to the visual/spatial learner.
Here’s how roots vocabulary works. You take apart a word such as expect, breaking it down into prefixes and roots that each mean something.
So expect= ex-e- (out, former) +spect-spic-spi (see, look, consider) = expect, to look out for.
