The Story Behind the Word

Sonder is a neologism — a newly coined word — created by writer John Koenig for his project The Dictionary of Obscure Sorrows, a creative endeavor dedicated to inventing precise words for emotions that have no name in any existing language. Koenig drew on German and French phonetic patterns to give the word a weight that felt older than it is.

Since its creation, sonder has spread widely online, resonating with people who recognize the feeling immediately but had never had a word for it. Its rapid adoption is a testament to how powerfully a well-named concept can fill a gap in human expression.

The Feeling It Names

Imagine sitting in a café, watching a stranger walk past the window. For a fraction of a second, you become aware: that person has a childhood full of specific memories. They have fears they've never spoken aloud, a favorite song, a person they're grieving, a dream they haven't given up on. Their inner life is as vast and detailed as yours — and yet to you, they are simply a silhouette passing by.

That flicker of awareness — that sudden re-scaling of the world — is sonder.

Example Sentences

  • Standing on the crowded platform, she was struck by a wave of sonder — every face around her holding an entire story she'd never know.
  • Travel, more than anything else, cultivates sonder — an awareness that the world is dense with lives as real as your own.
  • He described the feeling as a kind of quiet sonder — humbling and beautiful at the same time.

Why This Word Matters

Having a word for an experience makes you more likely to notice and appreciate that experience. Sonder is, at its heart, a word about empathy — the recognition that everyone around you is the protagonist of their own story, not merely a supporting character in yours.

In a world that increasingly filters experience through self-focused screens, sonder is a small but meaningful counterweight: a reminder to look outward.

Memory Tip

Think of the word wonder — and add an "s" for strangers. Sonder is the wonder you feel when you truly see a stranger as a full human being.

Using It in Conversation

While sonder isn't yet in major dictionaries, it's understood in literate, culturally aware circles — especially among language lovers, writers, and people who spend time online. Use it in:

  • Reflective writing or journaling
  • Conversations about empathy, travel, or city life
  • Essays exploring perspective and human connection

Add sonder to your vocabulary, and the next crowded street you walk down may feel quietly, profoundly different.
