These four terms are not synonyms, and getting them wrong is the single most common mistake visitors make. Here is the whole thing, in order of size.
England
One country. Capital London, population around 57 million. It is the largest and most populous of the four nations, which is why its name gets used — wrongly — for all of them.
Great Britain
The island containing three countries: England, Scotland and Wales. “Great” is not a boast; it distinguishes the larger island from Brittany in France, which was known as Lesser Britain.
This is a geographical term. It does not include Northern Ireland, which is why “Team GB” at the Olympics is technically a misnomer — the team includes Northern Irish athletes.
The United Kingdom
The country, and the political entity with a seat at the United Nations. Its full name is the United Kingdom of Great Britain and Northern Ireland. It is made up of four nations:
- England — capital London
- Scotland — capital Edinburgh
- Wales — capital Cardiff
- Northern Ireland — capital Belfast
This is the correct term for the state. Passports say United Kingdom, and the government is the UK government.
The British Isles
A purely geographical term for the whole archipelago — Great Britain, the island of Ireland, and around 6,000 smaller islands. It includes the Republic of Ireland, an entirely separate sovereign country, which is why many Irish people dislike the term and prefer “Britain and Ireland”.
Ireland: the important distinction
The island of Ireland contains two jurisdictions. The Republic of Ireland is an independent country, an EU member, with its own government, president and currency — it is not part of the UK in any sense. Northern Ireland, in the north-east, is part of the UK.
This distinction is not academic. It is the subject of a conflict that killed thousands of people within living memory, and it should be got right.
So what do I call people?
- British — safe for anyone from England, Scotland, Wales or Northern Ireland, though some in Northern Ireland and Scotland would not choose it for themselves.
- English — only for people from England.
- Scottish, Welsh, Northern Irish — the specific and usually preferred terms.
- Irish — for people from the Republic. Never call an Irish person British.
The safe rule: if you are not sure, say British. If you know where someone is from, use the specific term — it will be appreciated.
And “the Crown Dependencies”
One last wrinkle. The Isle of Man and the Channel Islands — Jersey and Guernsey — are not part of the UK at all. They are self-governing possessions of the Crown with their own parliaments and laws, defended by Britain but not governed by it.
