About the Author

Cherie A. Plant is a graduate in Elementary Education with a minor in Latin from the City University of New York, Cherie Plant is an accomplished etymologist (one who studies the origin and derivation of words). While teaching, Plant found that children as young as seven were fascinated with decoding words such as “triskaidekaphobia” (fear of the number 13) using the knowledge of prefixes, suffixes, and root words. Plant retired from teaching in 1995, but was convinced that other youngsters could benefit from such study. She has since devoted her time to writing language materials for all age groups, based on the study of Latin and Greek roots.
