High Quality Content by WIKIPEDIA articles! Interspel (from International English Spelling) is a set of principles introduced by Valerie Yule to meet the challenge of how to remove unpredictability and inconsistency from present English spelling while keeping the present heritage of print through minimal change in its appearance. That can be done when prevailing assumptions are challenged. The advantages of present spelling are maximized for users and learners by applying psychological research on their needs and abilities, facilitating both visual and auditory reading processes, and by taking account of the special features of the English language. This also promotes visible relationships of English and international vocabulary. Principles for systematization reduce present disadvantages. A phonemic spelling for beginners and dictionary pronunciation guides forms a base that then modifies. Such a combination of advantages has been claimed to be impossible. However, psychological and linguistic research and technological advances now make such a systematic reform more feasible, including breakthroughs by innovations that run counter to the usually expected proposals for spelling reform.
