The term Britain

The term “Great Britain” conventionally refers to the island of Great Britain, or politically to England, Scotland and Wales in combination.[51][52][53] It is sometimes used as a loose synonym for the United Kingdom as a whole.[54]

The term “Britain” is used both as a synonym for Great Britain,[55][56][57] and as a synonym for the United Kingdom.[58][57] Usage is mixed: the UK Government prefers to use the term “UK” rather than “Britain” or “British” on its own website (except when referring to embassies),[59] while acknowledging that both terms refer to the United Kingdom and that elsewhere ‘”British government” is used at least as frequent

ly as “United Kingdom government”.[60] The UK Permanent Committee on Geographical Names recognises “United Kingdom”, “UK” and “U.K.” as shortened and abbreviated geopolitical terms for the United Kingdom of Great Britain and Northern Ireland in its toponymic guidelines; it does not list “Britain” but notes ‘it is only the one specific nominal term “Great Britain” which invariably excludes Northern Ireland.'[60] The BBC historically preferred to use “Britain” as shorthand only for Great Britain, though the present style guide does not take a position except that “Great Britain” excludes Northern Ireland.[61][62]

The adjective “British” is commonly used to refer to matters relating to the United Kingdom and is used in law to refer to United Kingdom citizenship and matters to do with nationality.[63] People of the United Kingdom use a number of different terms to describe their national identity and may identify themselves as being British, English, Scottish, Welsh, Northern Irish, or Irish;[64] or as having a combination of different national identities.[65][66] The official designation for a citizen of the United Kingdom is “British citizen”.[60]
