Frank's compulsive guide to Postal Addresses:
What should be the name of this section? THE UNITED KINGDOM AND IRELAND (as it was once labeled), while technically correct if IRELAND is taken as the name of the country and not the island, can easily be misconstrued. THE UNITED KINGDOM AND THE REPUBLIC OF IRELAND would not be correct since there is no country whose name is REPUBLIC OF IRELAND. THE UNITED KINGDOM AND ÉIRE is correct (two non-overlapping countries) but it contains a mixture of languages. Hence BRITAIN AND IRELAND (two non-overlapping islands) -- perhaps not quite adequate either since it might not encompass the various associated outlying islands.
