Bilbo Baggins names his sword ‘Sting’ for a couple of reasons that reflect both his character development and the nature of the sword itself.
Firstly, when Bilbo acquires the sword from the trolls’ cave, he recognizes its significance and feels a sense of pride in possessing it. The name ‘Sting’ symbolizes his transition from a timid hobbit to someone who can defend himself and take on greater challenges. It marks the beginning of his journey where he becomes more courageous and adventurous.
Secondly, the name also describes the sword’s effectiveness, especially when used against the creatures Bilbo encounters. He realizes that it can ‘sting’ his enemies, particularly the spiders of Mirkwood, who are often a source of danger for him and his companions. In this sense, the name serves as both a metaphor for his newfound bravery and a literal description of the weapon’s potency.
Thus, naming the sword ‘Sting’ encapsulates Bilbo’s growth throughout the story and his emerging role as a hero, while also highlighting the weapon’s function in his adventures.
