The main purpose of this research is to improve the Hyper Dictionary and add a function which would be more useful for users to learn English words. The goal is to improve the classification of English words, Indo-European roots, and interim transitional words by adding definite meanings and addition meanings of English words in specialized fields, e.g., Mathematics, Medicine, and Computer science, etc. The task of other researchers in our laboratory is to add examples of English sentences that included links to jump to an English word's information page, a function to allow learners to hear native English pronunciation, and a database of suffixes of English words to the Hyper Dictionary. In addition, we added new English word and Indo-European root data, as well as required prefixes, interim transitional words, and stems of English words.
