Etymology: Ancient Greek "stoikheion" originally meant something like a row, line, or series, and it was used for the letters of the alphabet, which were arranged in a fixed sequence. Its sense then widened to the basic components of anything, and the Greek philosophers applied it to the fundamental substances of nature. Plato and Aristotle used the word for the elements of the physical world, a notion that later thinkers would develop into the idea of earth, water, air and fire as basic building blocks. Greek writers also used it to mean the first principles of a subject, so that a textbook of geometry, such as Euclid's, could be called "Elements" in the same sense. English took the word through Latin, where it became "elementum," and the Latin form gave English "element." The Greek term itself survives mainly in scholarly and philosophical contexts.
