Name of the northern region of Middle-earth or the ancient people who lived there (UT/14, LotR/1041), translated “North-region” or “Northmen” (Let/224, Ety/WEG). It is a combination of forod “north” and gwaith “people, region” (Ety/PHOR, WEG).
Conceptual Development: The name G. Forodwaith appeared in the earliest Lost Tales as a name for the “Men of the North” or Vikings (LT2/313), replacing earlier G. Gwasgonin “Winged Helms” (LT2/334). In The Etymologies from the 1930s, it appeared as both N. Forodwaith and N. Forodweith, reflecting Tolkien’s vacillation on the development of the diphthong [ai]; by this stage it already had the dual meaning given above (Ety/WEG, PHOR).
forod (“northern”) + gwaith (“people, folk”)
