LibreOffice - The Choice for Irish

We recommend it to anyone who is writing in Irish do download and use the free computer application called LibreOffice. This is an excellent wordprocessor that hosts a spellchecker and thesaurus, for example. One can make PDFs from documents easily as well.

In LibreOffice, it is possible to open MS Word documents, make changes, and save again as a MS Word document, if required.

An Foclóir Beag, the Irish/Irish dictionay, is available on line. It offers more than the print version; for example, one can see verbs and adjectives in all their forms.
