Just 25 most commonly used words make up about one-third of all words written or spoken in English. The first 100 most frequently used words make up about one-half of all written and spoken English. These are most commonly used and most important words when it comes to understanding and creating correct sentences. However, most of these words are not the nouns and verbs presented in most sight word collections. As well as the most commonly used nouns and verbs, they include the "glue" words without which understandable sentences cannot exist. These are words such as: "Yes," "No," "the," "not" "with," "and," "too," "very," "all" and many others. All these and many more of the most important and most frequently used words are effectively presented in both word and sentence form in this book.
