Holi

In the English language, 'Holi' sounds like a wholly (pun intended, sorry) appropriate name for a religious festival. But there seems to be little, if any, connection between this Hindi word and the English word 'holy'. According to National Geographic, "Holi gets its name from Holika, the demoness sister of evil King Hiranyakashyap in Hindu mythology. As the story goes, the villainous king tried to forbid his son Prahlad from worshiping one of the Hindu gods, Vishnu, but Prahlad persisted despite his father. So the king ordered Prahlad and Holika (who was immune to fire) to sit on a pyre, a wooden structure for burning a body as part of a funeral or execution. When the flames struck, Holika burnt to death in spite of her immunity to fire, and miraculously Prahlad prevailed because he called on the help of Lord Vishnu. So Holi celebrations serve as a reminder of the triumph of good over evil, reflecting the Hindu belief that faith and devotion leads to salvation that can be attained by everyone who believes."

Is there any connection between the name of the demoness in Hindu mythology, and the English word 'holy'? This question has been asked on Quora.com, and varous people have tried to answer it, but no one seems to have established any link.
