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, and for instructional videos, see FAQ How do I look up grammatical data? and FAQ How do I listen to sound files? respectively.

Latest News: January 2017

We’ve added 4,700 new entries to the dictionary, as well as 21,000 sound files (7,000 in each of the three main dialects).
This means that the site now has a total of 48,000 entries with 140,000 senses. Regular updates to the dictionary will continue indefinitely, but the list of headwords compiled at the start of the project has now been completed with the current upload.
