If you consider y a vowel, which I sometimes do, there aren't many words in the English language that contain all vowels with all of them in alphabetical order. Here are the ones I found:
- abstemiously - in a manner of having restraint, typically with respect to drinking alcohol. As in, "I'm not going to abstemiously not drink this entire bottle of apricot schnapps."
- adventitiously - if you don't intrinsically know the definition of adventitiously, perhaps one day you'll stumble upon it.
- facetiously - just (inappropriately) kidding!
- sacrilegiously - in a manner of receiving religion from a sac.
And only abstemiously and facetiously have all 6 vowels, only 6 vowels, and all of them in alphabetical order. So... now that's something we know.
