How many words one uses cannot be measured exactly? How ever, Professor Seashore conc luded that first-graders enters school with at leas t 24,000 words and add 5,000 each year so that they leave high school with at least 80,000. These figures are for recognition vocabulary, the words we understand when we read or hear them, which are more than our active vocabulary, the words we use in speaking and writing.

   U sing the words you recognize in reading will help get them into your active vocabulary. In your reading, pay attention to these words, especially when the subject is one that you might well write or talk about. Underline or make a list of words that you feel a need for and look up the ones you are not sure of in a dictionary. And then before very long find a way to use some of them. Once you know how they are pronounced and what they mean, you can safely use them.
