In this season of Braininess, we explore the evocative world of The Dictionary of Obscure Sorrows, created by John Koenig, a collection of invented words that capture emotions we’ve all felt but never had a name for. From the quiet ache of longing for something intangible to the fleeting sadness of unspoken moments, we dive into the subtle, often overlooked feelings that shape our inner lives. Join us as we uncover the science, psychology, and poetry behind these beautifully specific sorrows and reflect on the depth of human experience that often goes unnoticed.
