Content is simply defined as the meaning of information. Language contains words to describe virtually everything that we know about our world. These words describe objects, actions, events, and concepts. Meaning is typically found in words, but it also exist in part words (“-ed” means the past), and entire sentences that mean more than each individual word listed in random order (“The frog caught the fly with its long tongue”).

Typical children beyond the age of seven learn more than 700 new words and associated knowledge per year. Children who have moderate to severe vocabulary delays (measured by standardized tests) are at high risk of misunderstanding lessons and texts in the classroom. They may also lack the knowledge to engage in conversations with peers. New content needs to be learned almost every day and collaborated intervention with family and caregivers is critical. Delayed children who receive intensive intervention can close the gap with their same age peers.
