A noun translated “goblin, orc” and fully declined as an example of a Strong I noun (SD/436). Carl Hostetter and Patrick Wynne suggested (AAD/24) this form of the word may be a derivative of the contemporaneous Elvish root ᴹ√OROK. In later writings it appeared as Ad. urku/urkhu (WJ/390), a derivative of the Elvish root √RUK “terrible shapes”. This entry retains the form uruk because of its many attested inflections.

noun. Goblin, Orc
A Noldorin name for the “Goblin Gate” appearing only in the Lord of the Rings drafts from the 1940s, as both Annerchin and Annerchion (RS/416, TI/114). It seems to a combination of a shorter form of annon “gate” with a plural form of orch “Orc”, hence more literally “✱Gate of Goblins”. The function of the suffix -i(o)n is unclear; Roman Rausch suggested it might be a plural or genitive plural suffix (EE/1.8, 2.6).
