Both “country” and “nation” have a wide variety of definitions, and several of them overlap.
The definition you give for “nation” is a particular technical one used in certain contexts, but the word used for the way you define “country” in the context where that kind of technical definition is being used for “nation” is “state”, not “country”. (And even “state” may be used with additional qualifiers to disambiguate the exact sense when used for that, because it is a heavily-overloaded term.)
Nation and country are not interchangeable. Words have meaning. Good journalist choose their words deliberately and have a deeper understand of language than the average person.
For the common person and the common definition and use of the two words, they are very much interchangeable. The common person might not even notice the change in words because the generally used definitions of both are common enough.
I assume they’re alternating not because it’s AI written but because the author considered them synonymous and wanted it to sound less repetitive.
These words are just so overloaded that I think this is a lost battle. People hike in the back-country, you can live in the city or the country. And frankly if you used “nation” to represent a cultural group of people in almost any context I think people would not understand or worse - assume you were stoking some racial angst or land-dispute.
> There are many more nations than there are countries, especially within the US.
Each US state has "a political boundary, a flag and an anthem". So that's 50 of them. How many nations are there in the US?
This is, to say the least, not the only definition of a “country” (and is also among the definitions of “nation”.)
And I do mean "English" because in the UK, England, Scotland and Wales are officially considered "countries" by the UK government...
"And by 'country' we mean a sovereign state that is a member of the UN in its own right"
So if you're asked for "country names ending in land" on the show they'll invariably remind you of the definition and you ought to then know Scotland is plain wrong, whereas Ireland is a reasonable although obvious (so not "Pointless") attempt to answer.
I took this to include things like first nations and reservations which are themselves "sovereign".
