As the English language is constructed from root words, while common prefixes and suffixes are added to the root word to change the meaning. The trick is syllabication, a technique which allows students to separate words into small units which facilitates pronunciation along with phonics — an understanding of sound units. This course allows students to increase their vocabulary, retain vocabulary, and improve their spelling. Syllabications identify, root word building blocks/ divide words for pronunciation….
