What are core words?

Core words are a relatively small number of words (50-100) that make up most of what we say everyday. They can be hard to learn because they are more abstract, but they are what gives meaning to everything we say.

Fringe words are the rest of the words we use - they might occur less often or only in certain situations. Many times they are easier to explain with a picture and can be easier to learn. Many of our most motivating words are fringe words.

Take the word "cookie." If I say "cookie," you might think I want a cookie. Or maybe I'm saying no to cookies. I could be asking where the cookies are. I could be asking you if you want a cookie. "Cookie" is a fringe word. Words like "want," "no," "where," and "you" are all core words. They give meaning to the fringe words.
