quote:that which pertains to or belongs to 'Eire'
Sin 'Éir
eann', le 'nn' leathan!
(e.g. Dáil Éireann, Uachtarán na hÉireann)
Níl mé ró-eolach faoi na bandéithe a luaigh tú, ach seo díochlaonadh [=declension] an fhocail:
Éire = nominative
Éireann = genitive
Éirinn = dative, now used as nominative by some speakers/dialects.
