Where did the name "Durendal" came from?

Durendal (most likely from the French "durer") means "to endure". Durendal is the sword of Charlemagne's paladin Roland in the literary cycle known as the Matter of France. The origin of the sword received various accounts - several of the works of the Matter of France, however, agree that the sword was forged by Wayland the Smith, who is commonly cited as a maker of romantic weapons. According to the Song of Roland, the sword is brought by an angel to Charlemagne, who gives it to Roland.
