1. 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.
2. 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.
3. one of the ultimate parts which are variously combined in anything; ; 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.
4.
5. one out of several parts combined in a system of aggregation, when each is of the nature of the whole.
6. one of the smallest natural divisions of the organism, as a blood corpuscle, a muscular fiber.
7. one of the simplest essential parts, more commonly called cells, of which animal and vegetable organisms, or their tissues and organs, are composed.
8.
9. an infinitesimal part of anything of the same nature as the entire magnitude considered. in the calculus, element is sometimes used as synonymous with differential.
10. 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.
11. one of the terms in an algebraic expression.
12. one of the necessary data or values upon which a system of calculations depends, or general conclusions are based.
13. the simplest or fundamental principles of any system in philosophy, science, or art; rudiments.
14. any outline or sketch, regarded as containing the fundamental ideas or features of the thing in question.
15. one of the simple substances, as supposed by the ancient philosophers; one of the imaginary principles of matter.

20. to compound of elements or first principles.
21. to constitute; to make up with elements.

1. to compound of elements or first principles.
2. to constitute; form from elements; compose; enter into the constitution of.
3. that of which anything is in part compounded, which exists in it, and which is itself not decomposable into parts of different kinds; a fundamental or ultimate part or principle; hence, in general, any component part; any constituent part or principle.
4. specifically— an ingredient, especially of the temperament.
5. plural the rudimentary principles of any science: as, euclid's “elements” (gr.
6. in geometry, one of the points, lines, or planes, or other geometrical forms, by which a figure or geometrical construction is made up. “space may be considered as a geometrical figure whose elements are either points or planes. taking the points as elements, the straight lines of space are so many ranges, and the planes of space so many planes of points. If, on the other hand, the planes are considered as elements, the straight lines of space are the axes of so many axial pencils, and points of space are centers of so many sheaves of planes” (Cremona, Geom., tr. by Leuesdorff, § 31).
7. in mathematics, one of a number of objects arranged in a symmetrical or regular figure. the elements of a determinant are the quantities arranged in a square block or matrix, the sum of whose products forms the determinant.
8. in astronomy, one of the quantities necessary to be known in calculating the place of a planet (perhaps because the planets were called elements). they are six, namely, the longitude of the ascending node, the inclination of the orbit to the ecliptic, the longitude of the perihelion, the mean distance from the sun, the mean longitude at any epoch, and the eccentricity.
9. A datum required for the solution of any problem.
10. plural the bread and wine used in the eucharist: distinctively called communion elements.
11. in biology, one of the primary or embryological parts composing the body of an animal, or of the pieces which have united to form any part. thus, the thorax of an insect is composed of three principal elements or rings, the epicranium is formed of several elements or pieces which are soldered together, etc.
12. in electricity, a voltaic cell. see cell.
13. one of the four things, fire, water, earth, and air (to which ether was added as a fifth element), falsely regarded by the ancients as the constituents of which all things are composed.
14. A kind of matter undecomposable into other kinds.
15. there are a number of other bodies which have been named as elements (as phillipium, norwegium, etc.), whose properties have, however, not yet been sufficiently investigated and defined to warrant their inclusion in the list.
16. the proper or natural environment of anything; that in which something exists; hence, the sphere of experience of a person; the class of persons with whom one naturally associates, or the sphere of life with which one is familiar: as, he is out of his element.
