Derbyshire is a county in England, in the north of the country's middle — not London, and not the far north either. A 'shire' in an English county name is the old way of saying 'this city's land': Derby is the city, Derbyshire is the county around it. You will see the name on maps, train boards, and weather reports. The Peak District National Park, a famous place of hills and walking, lies mainly in Derbyshire, which is why tourist pages talk about the two together — though actually a piece of the park sits in the next counties as well, so 'the Peak District is Derbyshire' is a useful habit, not a perfect line on a map. It is only a place-name. You cannot buy 'a derbyshire' or be 'very derbyshire'. One more living detail: the city is spelled Derby but said DAR-bee, and the county name follows that, not the way the letters look.
