1) *peredhel (pl. peredhil) (PM:256, 348), 2) (actually ”Half-Noldo”) peringol (i beringol, o pheringol), pl. peringyl (i pheringyl), coll. pl. ?peringollath
Term for one with mixed human and elvish blood, almost always appearing in its plural form Peredhil as in The Lord of the Rings appendices (LotR/1034). It is a combination of per- “half” and Edhel “Elf” (SA/edhel).
Conceptual Development: In Silmarillion drafts from the 1930s, Tolkien used the term N. Peringol to refer to Elrond’s half-blood (LR/152), but this term was a combination of N. perin “half” and the root ᴹ√ÑGOL from which the tribal name ᴹQ. Noldo was derived, so literally meant “Half-Gnome [Noldo]” (Ety/PER).
