Or the next best thing, you could listen to a very enjoyable World Music programme introduced in Irish, and pick up phrases without noticing it. (I’m not biased at all! – Níl mé claonta ar chor ar bith!) Feel free to contact me if you have any questions about anything on the show. You will find the links by clicking on my user name. You can listen live or catch up with past shows on my podcasts. Go n-éirí leat! (Best of luck!)
