kenopsia
The haunting quality of seeing a location typically full of people in a state of emptiness or abandonment.
rare, uncountable
Many of the places we visited have the distinct feel of kenopsia, which is that eeriness of places left behind or once teeming with people but now quiet, save for the wind blowing through open windows.
Where it comes from
Coined by American author and neologist John Koenig, creator of The Dictionary of Obscure Sorrows, from Ancient Greek κενός (kenós, “empty”) and the modern English suffix -opsia, itself from the Ancient Greek -οψία (-opsía, “sight”).
