Did the Ring Need a Label?

[Aganzir]

Words have power in Middle-earth. Gandalf had to say Naur an edraith ammen in order to light the fire at Caradhras - he couldn't just snap his fingers.

I like G55's point about Sauron having to etch the verse into the Ring's being. There are also other instances of using writing/runes for magical purposes. I don't think the doors of Moria would function without the inscription, and I also seem to remember the dwarves put some runes on the troll hoard in the Hobbit. Perhaps they are needed to make an item remember the purpose for which it has been crafted.

Or then Sauron was just showy.
