I've noticed a tendency for more and more two-word phrases with even slightly idiomatic usage being written more and more as single word compounds. Today when I came across "everytime" written as a compound I looked to see how modern it was on Google Ngram Viewer and was surprised to see it much more common than I expected.
The question is do any traditional dictionaries yet grant it word status? Some online dictionaries like Wiktionary do, but it also includes the comparative and superlatives "more everytime" and "most everytime" so can hardly be trusted beyond a certain point.
Apart from the main question I was also surprised to see that this form peaked between 1970 and 1990 and is actually in decline again.
