@lmika Also, for the last few years, MacOS has been marking "earworm" as a spelling error, suggesting either "ear worm" or "ear-worm" as corrections. Yet, after doing a quick online search, it seems like "earworm" is a legitimate way to spell this word. I suppose those working on the Wikipedia page or the OED could've miss-spelt it also, but given MacOS's track record with spelling, I'm more incline to believe them.
