A Doriathrin noun for “horror” derived from the root ᴹ√ÑGÓROTH (Ety/ÑGOROTH). Its Noldorin cognate N. goroth indicates a primitive form ✱✶ŋgorotʰo, where the second o was lost due to the Ilkorin syncope. Ordinarily, an initial ng- became g- in Ilkorin, as noted by Helge Fauskanger (AL-Doriathrin/ngorth), and ngorth seems to be a variation on this rule.
