WHAT’S IN A NAME?

In view of recent dramatic events,terms such as deoxyribonucleic acid and endoplastic reticulum are fast becoming an essential part of the modern biologist's vocabulary.

Such further additions may well reinforce the false idea that biology, already famous (or infamous) for the length and seeming complexity of its terms, is strictly a «memory course». It probably seems to many students that biologists spend hours just sitting around and thinking up difficult words to be memorized.

In truth, it must be admitted that many biology terms are long and occasionally difficult to spell. However, there are at least two good reasons why this must be so. First of all, the biologist is faced with the need to name and describe an almost infinite number of different plants and animals, to say nothing of their parts. One cannot name just so many things using less than five or six letters. Thus the use of longer terms becomes a necessity.

Secondly, often the use of a longer term makes the word easier to recall. This is because the person who first coins the termfrequently tries to make his word descriptive. An examination of the roots and stems of many terms, not necessarily biological, will serve to make this idea clear.
