Teaching Irish is no problem for Clíodhna Ní Chorráin, a fluent speaker who has passed on a cúpla focal (a few words) to students from around the world. But doing it live on TV for Canada's national broadcaster ahead of St Patrick's Day? That was a real "pinch me" moment for the County Armagh woman.

St. Patrick’s Day has become a global celebration of Irish heritage, with the United States being the epicentre of festivities. Although originally a solemn religious day in Ireland, the celebration has evolved into a boisterous, cultural event in America, marked by parades, food, drinks, and, of course, the wearing of green.
