Language philosopher Ludwig Wittgenstein once wrote, “The limits of my language mean the limits of my world.”

Wittgenstein knew that his world was limited to the words he could use to describe it. This has been borne out through more methodical tests, like those performed by Johnson O’Conner. For over two decades he performed a variety of experiments to establish what factors turn a person into a success. The one factor that Johnson found to predict success, taking other variables into account, was vocabulary size. The larger the vocabulary, the better chances that the person would find their way into the C-Suite. The earlier children begin building vocabulary, the better their chances are for success in life.

Children start to understand words at 12-18 months, absorbing everything they hear. As they get older, they benefit from having their vocabulary expanded with more complicated words. By the time they are ready to start preschool and kindergarten, their vocabulary is advanced enough that they need to have discussions that improve their word knowledge. Kindergarten is the time when vocabulary differences become evident. A child from an affluent family will understand nearly twice the words that a child from a poor family. This is a gap that, if left unchecked, affects student learning.

Fortunately, many strategies are available to close that gap.

These small but necessary steps build a foundation for reading. The more words a student has in their possession, the easier it is for them to grasp new concepts in class. Building vocabulary encourages them to explore new concepts, opening them up to new ideas, that expose them to new words. A virtuous learning circle develops, giving every student a chance at success through high school graduation and beyond.
