The UK is the sovereign country, which has embassies in other countries. England, Scotland, Wales, and Northern Ireland are called "constituent countries" or "home nations" of the UK. Oh, and regarding Guru Hank s answer, the "Principality of Wales" is an obsolete term - it was abolished when Wales was formally united with England in 1542 and referred to an area which was considerably smaller than modern Wales anyway.
England, Northern Ireland and Scotland are all kingdoms that are United into one Kingdom, thus, United Kingdom. England, Scotland, Wales and Northern Ireland are all run under the British Parliament. Northern Ireland, Wales and Scotland do have their own parliaments, but only discuss matters that effect the country in minor ways, such as how much Scottish police officers are paid, or how well Welsh schools are run and so on.
So in a short answer, England, Scotland, Wales and Northern Ireland are all 4 countries, but not in the same sense that the US is a country, England, Scotland, Wales and Northern Ireland all all run under the United Kingdom which is a country in the same sense the US is.

Manx language in schools (Yn Ghaelg ayns ny scoillyn )
As part of government policy, the Manx language was introduced into schools by the Department of Education and Children in September 1992 as an optional subject for pupils aged 8 and over. This scheme has proved to be very successful and is highly popular with the children.
By order of the Education Act of 2001 'the curriculum shall include the provision for the teaching of Manx Gaelic and the culture and history of the Isle of Man'.
The four parts are non-sovereign countries. The UK is a sovereign country. Sovereign indicates that the country rules itself, which the parts don't.
Or to be more precise, Northern Ireland is a province because it never used to be a country by itself - the other three did.
The UK is a sovereign country the parts of it are not sovereign
Depends what language you are speaking, which in the Principality of Wales might not necessarily be English. This is a matter of semantics.
They are ALL separate Countries. Most of your Q does not make sense.
OUR UK is a COUNTRY/Nation State and the component parts are what we call HOME NATIONS or countries...Easy...Some have states, others provinces and we have what we have...Technically NI is a PROVINCE....
