A president is a leader of an organization, company, club, trade union, university, or country.

Etymologically, a president is one who presides, who sits in leadership (from Latin pre- "before" + sedere "to sit"; giving the term praeses). Originally, the term referred to the presiding officer of a ceremony or meeting (i.e., chairman), but today it most commonly refers to an official. Among other things, "President" today is a common title for the heads of state of most republics, whether popularly elected, chosen by the legislature or by a special electoral college.

Presidents in countries with a democratic or representative form of government are usually elected for a specified period of time and in some cases may be re-elected by the same process by which they are appointed, i.e. in many nations, periodic popular elections. The powers vested in such presidents vary considerably. Some presidencies, such as that of Ireland, are largely ceremonial, whereas other systems vest the President with substantive powers such as the appointment and dismissal of Prime Ministers or cabinets, the power to declare war, and powers of veto on legislation. In many nations the President is also the Commander-in-Chief of the nation's armed forces, though once again this can range from a ceremonial role to one with considerable authority.

An outro (sometimes "outtro", also "extro") is the conclusion or epilogue to a piece of music, work of literature, television program, or video game. It is the opposite of an intro. "Outro" is a blend or portmanteau as it replaces the element "in" of the "intro" with its opposite, to create a new word. The word was used facetiously by The Bonzo Dog Doo-Dah Band for the 1967 track "The Intro and the Outro".^{[citation needed]}

The term is typically used only in the realm of pop music. It can refer to the concluding track of an album (such as Snoop Doggy Dogg's Tha Doggfather) or to an outro-solo, an instrumental solo (usually a guitar solo) played as the song fades out or until it stops. For outro-solo examples see Led Zeppelin's "Black Dog",^{[citation needed]}Vanessa Carlton's "Home" (piano solo),^{[citation needed]}Eric Clapton's "Layla" (piano, guitar and slide guitar solo composed with Jim Gordon),^{[citation needed]}Pink Floyd' "Comfortably Numb",^{[citation needed]}Eagles' "Hotel California",^{[citation needed]}Metallica's "Fade to Black" and "Astronomy" (Blue Öyster Cult cover),^{[citation needed]}Tenacious D's "The Metal",^{[citation needed]}Guilherme Arantes' "Amanhã",^{[citation needed]}Dire Straits' "Tunnel of Love",^{[citation needed]}Rush's "Working Man",^{[citation needed]}Blur's "To the End (La Comedie)",^{[citation needed]} and T34's "Hbabi".^{[citation needed]}
