• n act A state of real existence, as opposed to a possibility, power, or being in germ merely; actuality; actualization; entelechy.
• n act The soul, according to the Aristotelians, is the act, that is, is the entelechy or perfect development of the body. So God is said to be pure act, for Aristotle says, “There must be a principle whose essence it is to be actual (η%148ς ἠ ον)σία ἐνε)ργεια),” and this is by many writers understood to mean “whose essence is to be active.” In the phrase in act, therefore, act, though properly meaning actuality, is often used to mean activity.

• n act The result of public deliberation, or the decision of a prince, legislative body, council, court of justice, or magistrate; a decree, edict, law, statute, judgment, resolve, or award: as, an act of Parliament or of Congress; also, in plural, proceedings; the formal record of legislative resolves or of the doings of individuals. Acts are of two kinds: general or public, which are of general application; and private, which relate to particular persons or concerns. A law or statute proposed in a legislative body, then called a bill, becomes an act after having been passed by both branches and signed by the chief executive officer; but in a few of the United States the governor's signature is not necessary. British acts are usually referred to by mentioning them simply by the regnal year and number of chapter: as, act of 7 and 8 Vict. c. 32. American acts, particularly acts of Congress, are often referred to simply by date: as, act of May 6, 1882.
• n act In universities, a public disputation or lecture required of a candidate for a degree of master. The performer is said to “keep the act.” Hence, at Cambridge, the thesis and examination for the degree of doctor; at Oxford, the occasion of the completion of degrees. So, act holiday, act feast. The candidate who keeps the act is also himself called the act. In medieval, and sometimes in modern scholastic use, any public defense of a thesis by way of disputation is called an act.
• n act [Such a synopsis (cedula), stating the time of studies, the acts made, and the degrees taken by the candidate, and duly sworn to, had usually been required in universities since the middle ages.]
• n act In law, an instrument or deed in writing, serving to prove the truth of some bargain or transaction: as, I deliver this as my act and deed. The term is used to show the connection between the instrument and the party who has given it validity by his signature or by his legal assent; when thus perfected, the instrument becomes the act of the parties who have signed it or assented to it in a form required by law. Edw. Livingston.
• n act In theology, something done at once and once for all, as distinguished from a work. Thus, justification is said to be an act of God's free grace, but sanctification is a work carried on through life.

• act To exert influence or produce effects: perform a function or functions; operate: as, praise acts as a stimulant; mind acts upon mind; the medicine failed to act; the brake refused to act, or to act upon the wheels.
• act To be employed or operate in a particular way; perform specific duties or functions: as, a deputy acts for or in place of his principal; he refused to act on or as a member of the committee. Often used with reference to the performance of duties by a temporary substitute for the regular incumbent of an office: as, the lieutenant-governor will act in the absence of the governor. See acting.
• act To perform as an actor; represent a character; hence, to feign or assume a part: as, he acts well; he is only acting.
• act He is a man of sentiment, and acts up to the sentiments he professes. Sheridan, School for Scandal, i. 2. Synonyms Act, Work, Operate. These words agree in expressing the successful exertion of power. In their intransitive use they are sometimes interchangeable: as, a medicine acts, works, or operates; a plan works or operates. Where they differ, act may more often refer to a single action or to the simpler forms of action: as, a machine works well when all its parts act. Act may also be the most general, applying to persons or things, the others applying generally to things. Operate, may express the more elaborate forms of action. Work may express the more powerful kinds of action: as, it worked upon his mind.
• n act A second act (1890) which provided for an annual appropriation, to be increased in ten years from $15,000 to a permanent sum of$25,000 from the proceeds of the sale of public land, for the more complete endowment of these institutions. This income could be applied only to instruction (with facilities) in agriculture, the mechanic arts, the English language, and other branches directly related to industrial life.
