It can be immensely helpful when one wishes to delve into the meaning of obscure words, particularly of the scientific or bio-medical sort. This dictionary is comprised mainly of an alphabetical listing of Greek and Latin roots, though commonly used roots and combining forms from other languages are included as well. There are also useful chapters on the formulation of scientific names, the transliteration of Greek words, and on common combining forms. This last chapter (the one on common combining forms) is particularly useful if your goal is to create new descriptive words as it is conveniently subdivided into descriptive categories (color, size, shape, animal structures, etc.).
