Sindarin name of the Southrons (LotR/245), a combination of harad “south” and the class-plural suffix -rim (Let/178).
Conceptual Development: In Lord of the Rings drafts from the 1940s, this name first appeared as N. Haradoth >> Haradhoth (WR/365), ending instead with hoth “host”.
harad (“south”) + rim (collective plural suffix)
