The Irish National Symbol is composed of two elements: the SHAMROCK and the HARP. The SHAMROCK, an 8-letter word, is a three-leaf clover that has been used to represent Ireland since the 16th century. It is believed to have been used by Saint Patrick to explain the Holy Trinity to the Irish people. The HARP, a 4-letter word, is a traditional Irish instrument that has been used for centuries to accompany Irish music. It is also featured on the national flag of Ireland and is used as a symbol of Irish identity. Together, the SHAMROCK and the HARP are the two main symbols of Irish Nationalism.
