SYNONYMS  base, basis, foundation, ground, groundwork. These nouns all pertain to what underlies and supports. Base is applied chiefly to material objects: the wide base of the pyramid. Basis is used in a nonphysical sense: “Healthy scepticism is the basis of all accurate observation” (Arthur Conan Doyle). Foundation often stresses firmness of support for something of relative magnitude: “Our flagrant disregard for the law attacks the foundation of this society” (Peter D. Relic). Ground is used figuratively in the plural to mean a justifiable reason: grounds for divorce. Groundwork usually has the sense of a necessary preliminary: “It [the Universal Declaration of Human Rights] has laid the groundwork for the world's war crimes tribunals” (Hillary Rodham Clinton).

adj., bas·er, bas·est.

1. 1. Having or showing a contemptible, mean-spirited, or selfish lack of human decency. See synonyms at mean².

[Middle English bas, low, from Old French, from Medieval Latin bassus.]

basely base'ly adv.
baseness base'ness n.

In the Brønsted-Lowry classification, any chemical species, ionic or molecular, capable of accepting or receiving a proton (hydrogen ion) from another substance. The other substance acts as an acid in giving up the proton. A substance may act as a base, then, only in the presence of an acid. The greater the tendency to accept a proton, the stronger the base. The hydroxyl ion acts as a strong base. Substances that ionize in aqueous solutions to produce the hydroxyl ion (OH), such as potassium hydroxide (KOH) and barium hydroxide [Ba(OH)₂], are also conventionally called bases.

Anions of weak acids such as acetic and formic, act as bases in reacting with solvent water to form the molecular acid and hydroxyl ion, for example, the acetate ion (CH₃COO⁻). Ammonia (NH₃) and amines react similarly in aqueous solutions. In these examples, the acetate ion and acetic acid (CH₃COOH) and NH₃ and the ammonium ion are conjugate base-acid pairs. The basicity constant, K_b, is the equilibrium constant for the proton transfer reaction, and it is a quantitative measure of base strength.

The Lewis classification involves the concept of a base as a substance that donates an electron pair to an acid aceptor. In the gas phase, NH₃ acts as a base contributing an electron pair to the formation of a convalent bond with the boron trifluoride (BF₃) molecule. See also Acid and base.

(1) A starting or reference point.

(2) In a bipolar transistor, the elements that act as a switch. In NMOS and PMOS transistors, which make up CMOS circuits, the base is called the "gate." See transistor.

(3) A multiplier in a numbering system. In a decimal system, each digit position is worth 10x the position to its right. In binary, each digit position is worth 2x the position to its right.

A period in which a stock price has very little or no trend. The resulting price pattern is a flat line.

Investopedia Says:
Basing is a common occurrence after a stock or the market has been in a lengthy decline or has increased by a large amount. In other words, the market is taking a break. Some stocks can form a base that lasts for severals years before the trend is reversed.

Any of a number of bitter-tasting, caustic materials. Technically, a material that produces negative ions in solution. A base is the opposite of an acid and has a pH of 7 to 14. A given amount of a base added to the same amount of an acid neutralizes the acid; water and a salt are produced. Alkalis are bases; ammonia is a common base.
