This reference aims to guide students and scientists from the fundamentals of word building to complete mastery of technical word meanings. It teaches ways to build scientific terms from Greek and Latin prefixes, suffixes, word roots and combined forms; methods of recognizing scientific words and meanings; and ways to learn the correct pronunciation of new terms. It covers terms used in chemistry, physiology, biology, anatomy, botany, earth science, physics, astronomy, and more. Using a programmed approach that stresses understanding the roots and parts of words, rather than memorization, the book offers a quick and easy way to learn and review thousands of scientific words and their pronunciations, spellings and definitions.
