Hodor was originally Wylis. When Bran was in a dangerous situation, he warged into Hodor's mind. This event somehow damaged Hodor's mind and left him only able to say 'Hodor'. It was a tragic event that changed Hodor's life completely.
Hodor's back story is complex. He started as Wylis, a young man in Winterfell. His life took a tragic turn. Bran, who had the power of warging, was in a tight spot and reached out with his mind. He entered Hodor's mind at a crucial moment. This connection, during a moment of extreme stress and danger, seemed to break something in Hodor's mind. As a result, his entire identity was reduced to just the word 'Hodor'. He went from being a normal person with a name, Wylis, to a person with a very limited mental capacity, only able to repeat that one word. It's a story of how a powerful and uncontrolled use of magic can have a devastating impact on an innocent bystander.
