n. a wistful omen of the first sign of autumn—a subtle coolness in the shadows, a rustling of dead leaves abandoned on the sidewalk, or a long skein of geese sweeping over your head like the second hand of a clock.

When I first read the word austice last week, it resonated perfectly with the day, the weather, and my mood. You would be forgiven if you are not familiar with the term. In fact, it was made up by John Koenig for his upcoming book The Dictionary of Obscure Sorrows. In recent years, Koenig has been the source for a number of surprisingly apt neologisms that presumably never appeared in English before, such as sonder, monachopsis, jouska,ambedo, and liberosis.

Here’s what Koenig’s publisher has to say about the release of his lastest book:

A truly original book in every sense of the word, The Dictionary of Obscure Sorrows poetically defines emotions that we all feel but don’t have the words to express, until now—from the creator of the popular online project of the same name.

Have you ever wondered about the lives of each person you pass on the street, realizing that everyone is the main character in their own story, each living a life as vivid and complex as your own? That feeling has a name: “sonder.” Or maybe you’ve watched a thunderstorm roll in and felt a primal hunger for disaster, hoping it would shake up your life. That’s called “lachesism.” Or you were looking through old photos and felt a pang of nostalgia for a time you’ve never actually experienced. That’s “anemoia.”

If you’ve never heard of these terms before, that’s because they didn’t exist until John Koenig began his epic quest to fill the gaps in the language of emotion. Born as a website in 2009, The Dictionary of Obscure Sorrows has garnered widespread critical acclaim, inspired TED talks, album titles, cocktails, and even tattoos. The Dictionary of Obscure Sorrows “creates beautiful new words that we need but do not yet have,” says John Green, bestselling author of The Fault in Our Stars.

By turns poignant, funny, and mind-bending, the definitions include whimsical etymologies drawn from languages around the world, interspersed with otherworldly collages and lyrical essays that explore forgotten corners of the human condition—from “astrophe,” the longing to explore beyond the planet Earth, to “zenosyne,” the sense that time keeps getting faster.

The Dictionary of Obscure Sorrows is for anyone who enjoys a shift in perspective, pondering the ineffable feelings that make up our lives, which have far more in common than we think. With a gorgeous package and beautifully illustrated throughout, this is the perfect gift for creatives, word nerds, and people everywhere.
