Only a few country names are accompanied by the definite article in English. These include the UK, the USA, the Netherlands, the Gambia, the Sudan, the Ukraine and the Lebannon. In some cases the definite article is only used occasionally – Sudan and Lebannon, for example, usually manage perfectly well without it. Why some countries are more definite than others is a bit of a mystery. Any suggestions?
In Welsh only some of countries have the definite article, though not the same ones as in English. Examples include yr Ariannin (Argentina), yr Aifft (Egypt), y Ffindir (Finland), yr Almaen (Germany), yr Eidal (Italy), yr Iseldiroedd (the Netherlands), yr Alban (Scotland), y Swdan (the Sudan), y Swistir (Switzerland) and yr Unol Daleithiau (the United States).
Most countries have the definite article in Irish, with the exception of Alba (Scotland), Ceanada (Canada), Cúba (Cuba), Gána (Ghana), Iosrael (Israel), Lucsamburg (Luxembourg), Meicsiceo (Mexico), Maracó (Marocco) and Sasana (England)
