Serendipity is the pleasant experience of finding something interesting or valuable by chance, especially something you weren't looking for.
What Does Serendipity Mean?
You go to the library for one book and come home with a different one that changes how you think. You miss your usual bus and end up sitting next to someone who becomes a close friend. Nobody planned any of that. That happy, unplanned discovery is serendipity.
Finding this café was pure serendipity: we only ducked in to escape the rain.
The classic ingredients are an accidental discovery, of something you weren't particularly seeking, that turns out to be interesting or valuable.
Pronunciation
se-ruhn-DIP-i-tee
The stress falls on the third part, "DIP." Say it a little like rapidity, just with "seren" on the front.
Natural Examples

- coincidence: two things lining up with no cause connecting them, and no particular value attached. Running into your dentist at the airport is a coincidence; it starts to feel like serendipity once something good comes out of it.
- chance: the neutral word for "not planned," used for good and bad accidents alike. Serendipity is chance, but chance with a happy ending.

In a Conversation
Priya: How did you two actually meet?
Sam: Total serendipity. I sat in the wrong lecture hall by mistake, and she was the only other person who'd done the same thing.
Priya: So being lost worked out pretty well for you.
Sam: Best wrong turn I ever took.
Where Does It Come From?
The word was coined in 1754 by the English writer Horace Walpole, in a letter to a friend. He based it on an old Persian fairy tale called The Three Princes of Serendip ("Serendip" being an old name for Sri Lanka, formerly Ceylon). In the story, the three princes kept making fortunate discoveries of things they weren't actually hunting for.
Walpole's own idea was more specific than just "luck": he described this kind of discovery as a mix of accidents and sagacity, noticing and making something of a chance you stumble across, not merely being handed it. The word spread slowly at first, staying obscure and rarely used for well over a century before it caught on more widely in the 20th century.
Easy Way to Remember It
Hear "serendip" inside serendipity, and picture those three princes from Serendip, stumbling onto treasures they never set out to find. You're not searching. You're just lucky enough to notice.
