The number of errors involving these three words appears to be endless.
Never-ending is an adjective meaning having no end or interminable, as in The Earth enjoys a never-ending supply of sunlight.
Neverending (one word) is a variant of the word that increasingly appears in print, probably due to publication of the German fantasy story The Neverending Story. The German word for never-ending – “unendliche” – doesn’t have a hyphen, so perhaps the translator didn’t think one was required in English. All of this confusion is compounded by the grammatically incorrect capitalization of the e in the title of the movie adaptation (The NeverEnding Story).
And the misspelling of the word as never ending just plain needs to, well, stop…
