A friend said she thought I must have some phobia about tidiness (what, me?) so I wondered if there is a word for such a condition. There wasn't but there is now, because I invented it.
Eutaxiophobia
Etymology : from Ancient Greek eu- (εὖ) "good" + taxis (τάξις) "arrangement" + phobia (φόβος) "fear"
Then I validated my new word by asking DeepSeek what it meant. It told me that it was not a commonly recognised word but if it existed it would mean "a fear or aversion to orderliness or tidiness", which fits the bill perfectly.
It's possible I am not the only person with this particular phobia.
