Aragorn's sword is called Andúril, which translates to "Flame of the West" in the Elvish language of Sindarin. It is also referred to as the "Sword that was Broken" or the "Reforged Sword." Andúril holds great significance in the story of "The Lord of the Rings."

Andúril was forged from the shards of the sword Narsil, which was shattered when Isildur, Aragorn's ancestor, cut the Ring from the finger of Sauron at the end of the Second Age. The shards of Narsil were kept as an heirloom of the Kings of Arnor and Gondor until they were reforged by the elf-smiths of Rivendell. The sword was then presented to Aragorn as he embraced his true identity and destiny as the rightful heir to the throne of Gondor.

As a symbol of Aragorn's lineage and his claim to the throne, Andúril carries great weight and importance throughout the story. It becomes a powerful emblem of hope and inspires courage in those who fight against the forces of darkness. The sword is depicted as a formidable weapon, and its gleaming blade and glowing aura reflect Aragorn's heroic qualities as a leader and warrior.
