почему соединенное королевство назвывают британией, англией и британскими островами
буду очень благодарна за ответ,заранее спасибо

It is known as 'Great' because it is the largest island in the British Isles, and houses the countries of England, Scotland and Wales within its shores. The name Britain derives from the Roman word Britannia, but there are two conflicting arguments about why the 'Great' was stuck on the front of it.
