Nibin-Nogrim
From Tolkien Gateway
One of the many variant names in Elvish for the diminuitive race known to Men as the Petty-dwarves. The word is related to Naugrim, the Elvish name for the true Dwarves. It refers to the Petty-dwarves as an entire race or people, and so presumably it would have been little used in the later First Age, as the Petty-dwarves of West Beleriand dwindled to a single family, and then at last became extinct.
