These lesson-by-lesson answer keys for Progress in Irish have been used by countless students in New England-area Irish classes since 1989, and have been gradually "proofread" through the years. They may, however, still contain the occasional error, and if you find any, please let us know. They are typeset as individual sheets, as they have been designed for use as hand-outs in Irish classes.
Many lessons of Progress in Irish contained an exercise simply titled "Léigh" (Read). We chose to reinterpret these as "Léigh agus cuir Béarla air seo" -- an extra opportunity to practice translating. Feel free to disregard these sections if you are a literalist.
There is often more than one "correct" way to express a thought in Irish. Máiréad Ní Ghráda relied heavily on the Caighdeán Oifigiúil in the creation of this book; every effort has been made to keep these answers "correct" within the context of Progress in Irish -- within the confines of the vocabulary & phrases which had been taught up to any given point where you might find yourself preferring some other answer.
We understand that the various dialects may have equally appropriate equivalents to these answers, but for the sake of brevity, and of consistency with Ní Ghráda's book, we have preferred answers derived solely from the teachings of Progress in Irish.
We hope that the countless students of Irish who will read and/or download these answer key sheets will appreciate Ní Ghráda's book all the more, now that they can check their work against the work of others.
