A term for the Dwarves as a race, translated “Stunted People” (S/91) or “Stunted Folk” (WJ/388), a combination of naug “stunted” and the class-plural suffix -rim (SA/naug, rim; WJ/388).
Conceptual Development: In earliest Lost Tales, the common collective term for the Dwarves was G. Nauglath (LT1/236), replaced with N. Nauglar or Nauglir in the Silmarillion drafts from the 1930s (SM/104, 311; LR/405). Later in the 1930s, the form Naug-rim emerged (LR/273), which Tolkien generally used thereafter.
A word for a Dwarf (WJ/388), a personalized form of the adjective norna “stiff, tough” (WJ/413), patterned after S. dorn.
