name. Orcs, (lit.) Din-horde, Host of Tumult
A collective term for Orcs, translated “din-horde” or “host(s) of tumult” (UT/54, MR/109, PE17/39). This name is combination of glam “din, uproar” and hoth “host, horde” (WJ/391, SA/hoth). This term was sufficiently common that it was generalized into another word for Orc: glamog (WJ/391).
Conceptual Development: The term G. Glamhoth was used for Orcs in the earliest Lost Tales (LT2/160), but at this early stage was translated “People of Dreadful Hate” with its initial element being G. glâm “hate” (GL/39). In the Etymologies from the 1930s, Tolkien revised the derivation of N. Glamhoth so that its initial element was N. glamm “shouting, confused noise; barbarous speech” (Ety/GLAM), and the term retained essentially the same derivation in later writings.
