This intuitive study of word components expands vocabulary.

The 14 Latin root sets have 5 roots for each of 3 Latin words. First students arrange the 15 roots (3 groups of 5) in a vertical column. Then they read the cloze sentences, attempt to predict the words, and add affixes to the roots to form words. Students learn to use the Latin root and prefix meaning, along with suffix part of speech, to analyze words and build vocabulary.
