From Tolkien Gateway

Fanuidhol was one of the three peaks in the Misty Mountains (with Caradhras and Celebdil) that lay above the ancient dwarf-city of Khazad-dûm.[1] A short name used by the Dwarves was Shathûr - in full Bundushathûr. It has the same meaning in Khuzdul as Fanuidhol in Sindarin - they both mean Cloudyhead.


In the common tongue, Fanuidhol was called "Cloudyhead". Both Bundushathûr and Fanuidhol translate to this.

Bundushathûr is Khuzdul - the first element "bund" means "head". Fanuidhol is Sindarin, where the second element "dol" means "head".
