Sting (Middle-earth)
Sting has the magical ability to detect orcs or goblins nearby, glowing blue in their presence, as it did when the Fellowship encountered orcs in the mines of Moria. Tolkien establishes this as a common property of First Age Elf blades, particularly those forged in Gondolin. Sting is also exceptionally sharp. Bilbo manages to thrust it without effort deep into a wooden beam at Rivendell. Frodo also wounds a troll in Moria, after Boromir notches his own sword with his attempt. Sam uses Sting to cut through the giant spider Shelob's strong webs with ease, and also wound the spider, driving it away from the paralyzed Frodo.
Frodo Baggins
In the early drafts of "The Lord of the Rings" the principal character is called Bingo Baggins; the name Frodo is given to another hobbit. In the drafts of the final chapters of "The Lord of the Rings" published by Christopher Tolkien as "Sauron Defeated", Gandalf names Frodo "Bronwe athan Harthad" (Endurance Beyond Hope) after the destruction of the Ring. Tolkien states that Frodo’s name in the fictional language of Westron was "Maura Labingi". His name in Sindarin (another of Tolkien's invented languages) appears to have been "Iorhael", which is derived from "ior" meaning "old" and "hael" meaning "wise". In "The Return of the King" he is also referred to by the name "Daur", a Sindarin word meaning "noble" (or perhaps "Wise by experience," if it means the same as "Frodo" does.)
