A Thesaurus of English Word Roots.pdf
Borror_Dictionary.Word.Roots.Combining.Forms.pdf
One of the outstanding problems of the biologist, whether he be
beginning student or specialist, is that of understanding technical
terms. The best way to understand and remember technical terms
is to understand first their component parts, or roots. To this end
the various word roots, from the Latin, Greek, and other languages,
that are most frequently encountered in biological terms have been
brought together in this dictionary.
Some of the word roots listed in the following pages are used in
many scientific terms and names, and once their meaning is understood
their occurrence in words subsequently encountered will immediately
suggest the meanings of the new words. The task of looking
up a new word in a technical or unabridged dictionary is often eliminated
by a knowledge of word roots. The study of the roots of words
can become extremely interesting, as well as a very valuable aid in
understanding new terms.
This dictionary has been designed primarily to meet the needs of
the beginning student, the medical student, and the taxonomist, but it
should be of value to all biologists. Both student and teacher are
keenly aware of the difficulties of the beginning student in learning
technical terms; the medical student is often overwhelmed by the
multitude of names of structures, conditions, and processes which
he must understand and remember; and the taxonomist frequently
encounters words the meanings of which are to be found only in a
Latin or Greek dictionary, if at all.
The section on the formulation of scientific names, following the
list of word roots, should be of value to the taxonomist
