Some confusion surrounds the question of what we should call the independent sovereign state that occupies 80% of the land area of the island of Ireland. That confusion is entirely understandable, and the purpose of this note is to remove it.
The
Irish Constitution of 1937 says: "The name of the State is Éire, or, in the English language,
Ireland".
The
Republic of Ireland Act, 1948, says: "It is hereby declared that the description of the State shall be the
Republic of Ireland."
Irish
passports simply bear the name
Ireland.
Irish government regulations and official statements frequently refer to "the
Republic of Ireland".
Comhairle, a statutory agency responsible for the provision of information, advice and advocacy to members of the public on social service, says on its web site:
'The names of political entities and other terms can often be quite contentious. The Irish and British governments have agreed to use the official names by which each state describes itself. (This agreement was made at the same time as the British-Irish Agreement). The correct name for this country is Ireland, not the "Republic of Ireland".'
.........so whilst it is strictly true that "Ireland" is the name of the republic, that does not mean that one should avoid the use of the phrase "Republic of Ireland", which frequently appears in directives, press releases and other official documents from the Irish government, as a search of their official web site at
http://www.irlgov.ie/ will readily show.
The advice stands: in many contexts it is safe and uncontentious to refer to the Republic simply as "Ireland". Where the possibility of ambiguity exists, use "the Republic of Ireland".
