A neologism for “destroyer” coined by Helge Fauskanger for his Neo-Quenya New Testament (NQNT), also appearing in the longer form nancarindo. These are based on nancar- which Tolkien glossed “undo”, but Fauskanger also used for “destroy”. I prefer ᴺQ. fehta- for “destroy”, and would use ᴺQ. fehtar for “destroyer”.
