‘An Caighdeán Oifigiúil’ - The Official Standard for the Irish language

‘An Caighdeán Oifigiúil’, the official written standard for the Irish language, was first published in 1958 under the title Gramadach na Gaeilge agus Litriú na Gaeilge – An Caighdeán Oifigiúil (‘The Grammar of Irish and the Orthography of Irish – The Official Standard’).

That publication laid out the grammar and orthography rules of Irish for those using the language for official purposes – in legislation, in official State publications, in the educational system, in the media and in various other fields. The ‘Caighdeán Oifigiúil’ was compiled in Rannóg an Aistriúcháin (The Translation Section of the Houses of the Oireachtas) and reprints were issued regularly between the years 1960 and 2004.

It was decided recently to prepare a new revised edition in order to modify or expand the scope of certain grammatical rules and to provide further clarity as regards some others. That revised standard (An Caighdeán Oifigiúil Athbhreithnithe), published by the Houses of the Oireachtas Service, is now available for purchase from the Government Supplies Agency, or an electronic version may be accessed here.
