The Progressive Speller is "progressive" because it begins with basic phonics and progresses to advanced vocabulary words. The words are categorized by the vowel sounds in the English language, and are broken down by syllables and accents. Reading passages show the words in context. As such, it is the only spelling book you will ever need.
*Each item labeled as "imperfect" may contain minor scuffs and scratches that in no way affect the use of the product.
