3. Ootrogue
It may look like outrage with its vowels confused, but an ootrogue is actually a sea undercurrent that pulls sand away from the shore. If you ever find your favourite beach stripped of sand, you can at least salvage a bit of fun by exclaiming: "I’m outraged by this ootrogue!”
'Refulgent'.
Not quite as non-ubiquitous as 'Ootrogue' ~ nor as weird-looking ~ but I've only used refulgent once about 10 years ago when I needed a good word to describe Hedda
10 years later I had to look it up again.
Not many words use three 'o's, so it's kind of lonely out there.
Cheers ... ( and just one more reason why I love living in Thailand )
