The language inscribed on the One Ring is known as Black Speech. It was created by the Dark Lord Sauron specifically for the purpose of commanding his followers and representing his malevolent influence. The inscription, which appears in Elvish script, is actually a phrase that translates to: ‘One Ring to rule them all, One Ring to find them, One Ring to bring them all, and in the darkness bind them.’
This language is characterized by its harsh sounds and is intended to evoke fear and submission. Sauron developed the Black Speech as a means to unify his followers under his dark will, making it a powerful symbol of his dominion over Middle-earth. When audiences encounter the inscription in the story, it serves to remind them of the overwhelming power and sinister nature of the One Ring.
