New English-Irish Dictionary

Welcome to Foras na Gaeilge's New English-Irish Dictionary, launched in January 2013. The dictionary is available free of charge, and has been adapted to work both on desktop computers and on mobile devices.

As well as translations for the English content, the dictionary also contains grammatical information and sound files. For more information on these latter items see FAQ How do I look up grammatical data? and FAQ How do I listen to sound files? respectively.

You can now search for a word or phrase in the Irish-language content of the New English-Irish Dictionary, and see all occurrences if it’s used in the dictionary.

But please note that the search in Irish is not as reliable or as comprehensive as the search in English, for a number of reasons. Further Information...

Some key features

Can’t find the headword you want?

Our dictionary is being published on a phased basis, and the full content won’t be online until summer 2016. We understand that it’s frustrating when you can’t find the word you need, and we’ll be continuing to expand the dictionary coverage in 2015 to close such gaps. But in the meantime, did you know that you can easily find many additional translations using the Advanced Search? See FAQ Finding translations with the Advanced Search for more details.

Want to see usage examples in Irish?

The Advanced Search is also very useful if you want to view examples of Irish usage – for example, is a particular preposition followed by a séimhiú? is a number followed by the singular or plural form of the noun? See FAQ Finding examples of Irish usage for more details.

Terminology –

If the word you’re looking for isn’t yet online in our dictionary, and if it’s a technical term, you may wish to search for it in our terminology database,
