Horace G. Danner’s A Thesaurus of English Word Roots is a compendium of the most-used word roots of the English language. As Timothy B. Noone notes in his foreword: “Dr. Danner’s book allows you not only to build up your passive English vocabulary, resulting in word recognition knowledge, but also gives you the rudiments for developing your active English vocabulary, making it possible to infer the meaning of words with which you are not yet acquainted. Your knowledge can now expand and will do so exponentially as your awareness of the roots in English words and your corresponding ability to decode unfamiliar words grows apace. This is the beginning of a fine mental linguistic library: so enjoy!” In A Thesaurus of English Word Roots, all word roots are listed alphabetically, along with the Greek or Latin words from which they derive, together with the roots’ original meanings. If the current meaning of an individual root differs from the original meaning, that is listed in a separate column. In the examples column, the words which contain the root are then listed, starting with their prefixes, for example, dysacousia, hyperacousia. These root-starting terms then are followed by terms where the root falls behind the word, e.g., acouesthesia and acoumeter. These words are followed by words where the root falls in the middle or the end, as in such terms as bradyacusia and odynacusis.. In this manner, A Thesaurus of English Word Roots places the word in as many word families as there are elements in the word. This work will interest linguists and philologists and anyone interested in the etymological aspects of English language.

This book lists almost 1,500 roots of academic, professional, and technical words. This is not a thesaurus in the common sense. Unlike the familiar collection of synonyms, this thesaurus gathers words with the same root words with similar meaning. The authors have distinguished a variety of these word elements and given them technical names, such as Simple Root, Prefixed Root, Leading Root Compound, and Trailing Root Compound. Horace Danner and Roger NoÎl's previous books include An Introduction to an Academic Vocabulary (UPA, 1990) which is recommended as a companion to this thesaurus.

Dr. Horace Gerald Danner’s A Thesaurus of Medical Word Roots is a compendium of the most-used word roots of the medical and health-care professions. All word roots are listed alphabetically, along with the Greek or Latin words from which they derive, together with the roots’ original meanings. If the current meaning of an individual root differs from the original meaning, that is listed in a separate column. In the examples column, the words which contain the root are then listed, starting with their prefixes. For example, esthesia, which means “feeling,” has as its prefixed roots alloesthesia, anesthesia, and dysesthesia. The listing then switches to words where the root itself forms the beginning, such as esthesiogenesis or esthesioneuroblastoma. These root-starting terms then are followed by words where the root falls in the middle or the end, as in acanthesthesia, cryesthesia, or osmesthesia. In this manner, A Thesaurus of Medical Word Roots places the word in as many word families as there are elements in the word. This work will interest not only medical practitioners but linguists and philologists and anyone interested in the etymological aspects of medical terminology.

Contains alphabetically arranged entries that explore the origin, evolution, and social history of over three thousand English language words.
