March 17th is the feast day of the patron saint of Ireland, St. Patrick. In the United States, it is also the day of shamrocks, leprechauns, and green beer (and green everything else). Blue was once the color traditionally associated with St. Patrick, but the color green has several links to Ireland, including its use on Ireland’s flag in the form of a stripe, its symbolism of Irish nationalism and the country’s religious history, and its connection to Ireland’s nickname, The Emerald Isle. On St. Patrick’s Day, people turn to their dictionary to look up Erin go bragh, which means “Ireland forever.” The original Irish phrase was Erin go brách (or go bráth), which translates literally as “Ireland till doomsday.” It’s an expression of loyalty and devotion that first appeared in English during the late 18th-century Irish rebellion against the British.
