This book presents a compilation of terms frequently encountered in the vocabulary of medicine. You will find a dash (-) appended to indicate that this word is incomplete, and there is something which comes before the medical term or behind the medical term. The terms, in this work, provide a map for students to begin to understand a complex language as the various component of the words (roots, suffixes, prefixes) are strung together to form a complete word..
