This dictionary provides the user with the basic vocabulary currently being used in a wide range of healthcare situations. The areas covered include the technical language used in diagnosis, patient care, surgery, pathology, general practice, pharmacy, dentistry and other specialisations, as well as anatomical and physiological terms. Informal, everyday and sometimes euphemistic terms commonly used by people in discussing their condition with healthcare professionals are also included, as are common words used in reading or writing reports, articles or guidelines.

The dictionary is designed for anyone who needs to check the meaning or pronunciation of medical terms, but especially for those working in health-related areas who may not be healthcare professionals or for whom English is an additional language. Each headword is explained in clear, straightforward English. Pronunciations, uncommon plurals and uncommon verb forms are provided. Illustrations of some basic anatomical terms are also included.

Very many people have helped or advised on the compilation and checking of the dictionary in its various editions. In particular, thanks are due to Dr Judith Harvey for her helpful comments and advice on this fourth edition and to Dr Marie Condon for some revisions and clarification. Also to Lesley Bennun, Lesley Brown and Margaret Baker who copy-edited the text and Dinah Jackson who revised the pronunciations.

While every effort has been made to be as accurate as possible, the author, advisers, editors and publishers of this book cannot be held liable for any errors and omissions, or actions that may be taken as a consequence of using it.
