Mr.

Mister, usually written in its abbreviated form Mr. (US) or Mr (US & UK), is a commonly-used English honorific for men under the rank of knighthood. The title derived from earlier forms of master, as the equivalent female titles Mrs, Miss, and Ms all derived from earlier forms of mistress. Master is sometimes still used as an honorific for boys and young men, but its use is increasingly uncommon.

The modern plural form is Misters, although its usual formal abbreviation Messrs(.) derives from use of the French title messieurs in the 18th century.Messieurs is the plural of monsieur (originally mon sieur, "my lord"), formed by declining both of its constituent parts separately.

Historic etiquette

Historically, mister—like Sir or my lord—was applied only to those above one's own status in the peerage. This understanding is now obsolete, as it was gradually expanded as a mark of respect to those of equal status and then to all gentlemen. It is now used indiscriminately.

In past centuries, Mr was used with a first name to distinguish among family members who might otherwise be confused in conversation: Mr Doe would be the eldest present; younger brothers or cousins were then referred to as Mr Richard Doe and Mr William Doe and so on. Such usage survived longer in family-owned business or when domestic servants were referring to adult male family members with the same surname: "Mr Robert and Mr Richard will be out this evening, but Mr Edward is dining in," but such usage today is rare in American culture but still quite common in others as a sign of respect when first names are being used, the last name is not known, or where English is not the mother tongue.

He began his presidential campaign in 2007 and, after a close primary campaign against Hillary Rodham Clinton in 2008, he won sufficient delegates in the Democratic Party primaries to receive the presidential nomination.

White House

The White House is the official residence and principal workplace of the President of the United States, located at 1600 Pennsylvania Avenue NW in Washington, D.C. It has been the residence of every U.S. president since John Adams in 1800.

The house was designed by Irish-born James Hoban and built between 1792 and 1800 of white-painted Aquia Creek sandstone in the Neoclassical style. When Thomas Jefferson moved into the house in 1801, he (with architect Benjamin Henry Latrobe) expanded the building outward, creating two colonnades that were meant to conceal stables and storage. However, in 1814, during the War of 1812, the mansion was set ablaze by the British Army in the Burning of Washington, destroying the interior and charring much of the exterior. Reconstruction began almost immediately, and President James Monroe moved into the partially reconstructed Executive Residence in October 1817. Construction continued with the addition of the South Portico in 1824 and the North in 1829.
