What is sword in beowulf?

The sword in Beowulf is called Hrunting, and it is a magical sword given to Beowulf by Unferth, a warrior of King Hrothgar's court. Hrunting's name means "bitter" or "sharp" in Old English, and it was said to have never failed in battle.

When Beowulf faces the demon Grendel's mother in her lair beneath the lake, Hrunting fails him, and he must rely on an enormous sword he finds in the lair. Later, he returns Hrunting to Unferth, admitting that it was not powerful enough to defeat Grendel's mother.

The sword plays an important symbolic role in the poem, representing the power and prestige of the warrior who wields it. It is also a reminder of the power of words and the importance of loyalty: Beowulf takes the sword not just as a weapon, but as a token of Unferth's trust and friendship.
