Everything below was done by someone else’s research.
I googled “word with all vowels in correct order”
The shortest and most common word I found that meets your criteria
is “facetious”. “facetiously” also contains the vowels in the right order and
even has a ‘y’ at the end as an added bonus. Here is a list of other words
that meet your criteria in the strictest sense, with no vowels occurring
outside of their allotted place:
abstemious
abstemiously
abstentious
adventitious
adventitiously
arenicolous
arsenious
cavernicolous
Here are some other words that have all five vowels in the correct order, but
also contain some duplicate vowels which are out of order:
abstemiousness
abstemiousnesses
adenocarcinomatous
amentiferous
anemophilous
antireligious
argentiferous
arteriovenous
autoecious
autoeciously
facetiousness
facetiousnesses
garnetiferous
sacrilegious
sacrilegiously
sacrilegiousness
sacrilegiousnesses
ultraserious
