dûm `excavations, halls, mansions', a plural or collective in Khazad-dûm (S:337) and possibly in Carn Dûm. A possible genitive form -dûmu appears in the word Khazaddûmu, q.v.
FELEK `hew rock' a root, (PM:352).
felak 1) a tool like a broad-bladed chisel, or small axe-head without haft, for cutting stone, 2) to use this tool (PM:352). We would also have to offer felak `hewer' (an agental noun) based on the entry which follows.
felakgundu `cave-hewer' (borrowed into Sindarin as Felagund, a name of Finrod, S:330, PM:352).
Fundinul `(son) of Fundin', Fundin is apparently a Mannish word, but the ending must be Dwarvish, posssibly a genitive, I 416.
gabil `great', isolated from Gabilgathol and Gabilan
Gabilân, a name of the river Gelion (WJ:336). Apparently includes gabil `great'.
Gabilgathol `Great fortress', Sindarin Belegost (S:91, 319; LR:274, WJ:389)

Gundabad, in Mount Gundabad (on the map in UT). Originally the language was not identified and this suggestion was based on the similarity to Dwarvish words uzbad and -gundu; however in PM:301 it is stated that Gundabad is `in origin a Khuzdul name'.
gundu `underground hall' (from root gunud) (PM:352). An element -gund(u) appears in Felak-gundu, and possibly in Gundabad and Nargûn.

Khazad-dûm `Mansion of the Khazвd, Dwarrowdelf' referring to Moria (I 370, S:44, 91, WJ:389, PM:24). Orignially, spelled Khazaddûm and identified with the `Dwarfmine' of Nogrod (LR:274). The spelling Khazaddûmu, appearing on Balin's Tomb, seems to be a genitive for `of Khazad-dûm' (I 416).

Rukhs `Orc', pl. Rakhâs (WJ:391).
Sharbhund `Bald Hill?', petty-dwarves' name for Amon Rudh (UT:98). [The first element is similar to the Orkish or Black Speech word sharkû, source of the epithet Sharkey, a name of Saruman and said to mean `old man' III 511. If Dwarvish and Orkish are related, shar- might mean `bald-' a suitable epithet for an old man. The second element is similar to bund(u) `head' which is a common metaphor for `hill' as may be seen in Quenya nуla, and S. dфl; (Etym. NDOL-).]
shathûr `cloud(s)', basic element probably `cloud', possibly plural. Shathûr is also a short name of Bundushathur `Cloudyhead', one of the mountains of Moria (I 370, TI:174)

Tumunzahar `Hollowbold', or Nogrod, a city of the Dwarves in the Blue Mountains, (S:91, 344, UT:389). It seems to have the elements tumun `hollow' (similar to Q. tumbu `hollow, swell') and zahar `bold, a building' (a noun form).
-u `in/of' in Bund-u-shathûr `head in/of clouds' (TI:174). This may be a genitive marker, as noted by Jim Allan, ItE:164.

ûl `streams' in Azanulbizar (RS:466)
-ul, adjectival suffix possibly, in the words Khûzdul `Dwarvish', Fundinul `[son] of Fundin' and in Mazarbul. This was also noted by Jim Allan, ItE:164.
Uruktharbun `Moria?' language identified as Khûzdul. (RS:458, 465). It seems to have been replaced by Khazad-dûm, though since it seems to have an element meaning `ork' in it, it may be a name of the location which acknowledges the then current control by another group.
uzbad `lord' used of the Dwarf Kings of Moria. (I 416).
zâram `glass' (in Narag-zâram and Kheled-zaram, RS:466) or `lake' per Jim Allan, ItE:164. These two meanings may not be in conflict, since a pool of water in an underground cavern has a remarkable property of reflection and so might come to be a routine metaphor used to mean `glass'.
ZGL, tri-consonantal root seen in zigil `spike' [but see Zigilnad], (TI:174)
zigil `spike (smaller and more slender than a horn)' in Zirak-zigil `Silver-spike' (TI:174).

zirak `silver' in Zirak-zigil `Silvertine, Silverspike'. [It says in LotR (I 413) that "the Dwarves have a name for it [mithril] which they do not tell." Nevertheless, this may be it, since it seems to mean `grey', (see ZRK), and this is an element in the meaning of the word mithril. Otherwise, we have two words for `silver (metal)'.] Zirak is also a short name of Zirak-zigil (TI:174) and is found in the name Gamil Zirak.
Zirakinbar `Silverhorn' (see inbar), replaced by Zirak-zigil `Silvertine'. (SD:45).
Zirak-zigil `Silvertine', one of the mountains of Moria (Sindarin Celebdil) I 370, TI:174.
ZN `dark, dim' bi-consonantal root seen in Azanulbizar, (RS:466). [This may possibly have a form *azan as an independent word.]
ZRK `silver, for its grey color' tri-consonantal root seen in zirak, Zirak-zigil, (TI:174).
