is a Latin word that is the origin of the English word "authority". While historically its use in English was restricted to discussions of the political history of Rome, the beginning of phenomenological philosophy in the 20th century expanded the use of the word.

In ancient Rome,  referred to the level of prestige a person had in Roman society, and, as a consequence, his standing, influence, and ability to rally support around his will.  was not merely political, however; it had a numinous content and symbolized the mysterious "power of command" of heroic Roman figures.

Noble women could also achieve a degree of . For example, the wives, sisters, and mothers of the Julio-Claudians had immense influence on society, the masses, and the political apparatus. Their  was exercised less overtly than that of their male counterparts due to Roman societal norms, but they were powerful nonetheless.

Etymology and origin
According to linguist Emile Benveniste,  (which also gives us English "author") is derived from Latin  ("to augment", "to enlarge", "to enrich"). The  is "", the one who augments the act or the juridical situation of another. Arguably, Benveniste defended that Latin "" was based on a divine conception of power and not on the individual that happened to the position of authority.

 in the sense of "author", comes from  as founder or, one might say, "planter-cultivator". Similarly,  refers to rightful ownership, based on one's having "produced" or homesteaded the article of property in question – more in the sense of "sponsored" or "acquired" than "manufactured". This  would, for example, persist through an  of ill-gotten or abandoned property.

Political meaning in ancient Rome
Politically, the Roman Senate's authority () was connected to —not to be confused with  or , which were held by the magistrates or the people. In this context,  could be defined as the juridical power to authorize some other act.

The 19th-century classicist Theodor Mommsen describes the "force" of  as "more than advice and less than command, an advice which one may not ignore." Cicero says of power and authority,  ("While power resides in the people, authority rests with the Senate.")

In the private domain, those under tutelage (guardianship), such as women and minors, were similarly obliged to seek the sanction of their  ("protectors") for certain actions. Thus,  characterizes the : The pater familias authorizes—that is, validates and legitimates—his son's wedding . In this way,  might function as a kind of "passive counsel", much as, for example, a scholarly authority.

In traditional imperial Rome, exceptions could be made to override legal concepts and rules of law under specific military and political situations. This authority allowed the imperial power to safeguard the state and its citizens. In cases where it was necessary to protect the state, a dictator could be appointed by the senate to temporarily override the fundamental laws and rules of the Roman Constitution.

After the fall of the Republic, during the days of the Roman Empire, the Emperor had the title of  ("first citizen" of Rome) and held the —the supreme moral authority—in conjunction with the  and —the military, judicial, and administrative powers. That is to say, there is a non-committal to a separation of powers, some civil rights, constitutionalism, codified constitutional state and legalist concept of law.

Middle Ages

The notion of  was often invoked by the papacy during the Middle Ages, in order to secure the temporal power of the Pope. Innocent III most famously invoked  in order to depose kings and emperors and to try to establish a papal theocracy.

Hannah Arendt 
Hannah Arendt considered  a reference to founding acts as the source of political authority in ancient Rome. She took foundation to include (as  suggests), the continuous conservation and increase of principles handed down from "the beginning" (see also ). According to Arendt, this source of authority was rediscovered in the course of the 18th-century American Revolution (see "United States of America" under Founding Fathers), as an alternative to an intervening Western tradition of absolutism, claiming absolute authority, as from God (see Divine Right of Kings), and later from Nature, Reason, History, and even, as in the French Revolution, Revolution itself (see ). Arendt views a crisis of authority as common to both the American and French Revolutions, and the response to that crisis a key factor in the relative success of the former and failure of the latter.

Arendt further considered the sense of  and  in various Latin idioms, and the fact that  was used in contradistinction to – and (at least by Pliny) held in higher esteem than – , the artisans to whom it might fall to "merely" build up or implement the author-founder's vision and design.
