"Over 60 percent of all English words have Greek or Latin roots; in the vocabulary of the sciences and technology, it's over 90 percent. Now in its third edition, The Greek & Latin Roots of English is one of the foremost resources for students of etymology. The newest edition retains the tried-and-true approach of previous editions, but includes even more resources for students. New exercises have been added to the end of each chapter, and many lessons are revised, updated, and expanded. Containing thematic chapters on word roots in biology and medicine, science and mathematics, politics and government, literature, and religion and philosophy, The Greek & Latin Roots of English is as valuable to students of medicine and the sciences as it is to students of language and the classics.
