Question from a Reader - England vs Great Britain

Reader Question:
"I always thought that the words England and Great Britain meant the same thing. But I just overhead something last week...someone said that GB includes England, Ireland, and
maybe Scotland. Can you confirm this? It would be much appreciated."

I asked a British cohort mate to help clarify:

"England is just one of the countries that make up Great Britain. Great Britain is the actual island we're sitting on and its outliers. The UK is Great Britain and Northern Ireland combined.

See if this Wikipedia def helps:

Great Britain is no longer a country, but simply an island in the United Kingdom. Politically, "Great Britain" describes the combination of England, Scotland, and Wales, and therefore also includes a number of outlying islands such as the Isle of Wight, Anglesey, the Isles of Scilly, the Hebrides, and the island groups of Orkney and Shetland, but does not include other outlying islands such as the Isle of Man or the Channel Islands.

The UK became the United Kingdom of Great Britain and Northern Ireland in 1922 following the independence of five-sixths of Ireland as first the Irish Free State, a Dominion of the then British Commonwealth, and then later as an independent republic outside the British Commonwealth as the Republic of Ireland."
