I love learning new words. (And writing them down.) All the better when they are invented words. John Koenig’s Dictionary of Obscure Sorrows is a collection of words Koenig has created—inspired by real etymology—for specific emotions that don’t have precise English words to describe them. Tell me you haven’t felt every one of these:

Sonder: (n) The realization that each passerby has a life as vivid and complex as your own

Opia: (n) The ambiguous intensity of looking someone in the eye, which can feel simultaneously invasive and vulnerable

Monachopsis: (n) The subtle but persistent feeling of being out of place.

Énouement: (n) The bittersweetness of having arrived in the future, seeing how things turn out, but not being able to tell your past self.

Vellichor: (n) The strange wistfulness of used bookshops.

Rubatosis: (n) The unsettling awareness of your own heartbeat.

Kenopsia: (n) The eerie, forlorn atmosphere of a place that is usually bustling with people but is now abandoned and quiet.
