Element


Definition:

  • (n.) One of the simplest or essential parts or principles of which anything consists, or upon which the constitution or fundamental powers of anything are based.
  • (n.) One of the ultimate, undecomposable constituents of any kind of matter. Specifically: (Chem.) A substance which cannot be decomposed into different kinds of matter by any means at present employed; as, the elements of water are oxygen and hydrogen.
  • (n.) One of the ultimate parts which are variously combined in anything; as, letters are the elements of written language; hence, also, a simple portion of that which is complex, as a shaft, lever, wheel, or any simple part in a machine; one of the essential ingredients of any mixture; a constituent part; as, quartz, feldspar, and mica are the elements of granite.
  • (n.) One out of several parts combined in a system of aggregation, when each is of the nature of the whole; as, a single cell is an element of the honeycomb.
  • (n.) One of the smallest natural divisions of the organism, as a blood corpuscle, a muscular fiber.
  • (n.) One of the simplest essential parts, more commonly called cells, of which animal and vegetable organisms, or their tissues and organs, are composed.

In the calculus, element is sometimes used as synonymous with differential.
  • (n.) Sometimes a curve, or surface, or volume is considered as described by a moving point, or curve, or surface, the latter being at any instant called an element of the former.
  • (n.) One of the terms in an algebraic expression.
  • (n.) One of the necessary data or values upon which a system of calculations depends, or general conclusions are based; as, the elements of a planet's orbit.
