What's this place called again? The British Isles, The United Kingdom, Great Britain, England, Scotland, Wales, Northern Ireland, Ireland - It's all very confusing
Citizens of the United Kingdom are British, which is where the confusion starts as "Britain" while commonly used and understood doesn't really refer to a geographic area though is often used interchangeably for "United Kingdom".
While citizens of all of the component parts of the United Kingdom may be referred to as British, you should be aware of is that "British" is NOT the same as "English". Referring to one of the 16% who is British but not from England as "English" will probably result in a correction on a scale of a jokey "It's ok, but.." - to terse and tight lipped.

Got that? Don't worry, many British people would have some difficulty in explaining it all too, just don't go calling everyone English when they might not be, even if they are British.
Strictly speaking the citizens of the UK are British and not English, Scottish, Welsh or Northern Irish, there is however no consensus as to how the terms should be applied and so everyone essentially has a catch-all nationality of British and then a more specific one as well.
The Republic of Ireland is part of the British Isles but is not part of the United Kingdom or Britain.
There is often confusion at many levels, for instance our team in the Olympics and some other sporting events is called "Team GB" for Great Britain when that is just the name of the largest island, "Team UK" would be more accurate, but GB it is.
I get a regular reminder when filling in any online form that asks for my nationality with a huge drop down list and have 3 different places to look for a choice when there's only any one of the 3 there, England, Great Britain or United Kingdom.
