Terminology of the British Isles There have been several suggestions for replacements for the term "British Isles". Although there is no single accepted replacement, the terms "Great Britain and Ireland", "The British Isles and Ireland" and "Britain and Ireland" are all used. The word "England" is often used synecdochically to refer to Great Britain—or the United Kingdom as a whole—which often causes offence, particularly to those from the non-English parts of Britain. In a similar way, references to England as an island, to an "English passport", or to Scottish or Welsh places as being in England are examples of this usage of the term "England".
