The correct answer is a harp.
The symbol of Ireland that is hidden in the word is a harp.
This refers to a famous riddle given in Saint Patrick’s Day. After the Leprechaun and the Shamrock, the harp is one of the most important symbols for the Irish. It is said that the arms of the harp represent the arms of the King of Ireland. Later, the arms were adopted by King Henry VIII of England after the period known as the Lordship of Ireland. It was until 1922 that the harp was considered a national symbol of the free-Ireland after the separation of England.
