To be wistful is to have sad thoughts and feelings about something that you want to have or do, and especially about something that made you happy in the past. Wistful can also describe something, such as a smile or sigh, that shows or communicates such feelings.

"Postcards have always been an object of fascination for me. I remember flipping through photo albums as a young girl and coming across those sent to my parents, from people I had never met. When I asked who these people were, I would hear wistful stories." — Minoli Wijetunga, The Guardian (London), 10 Jan. 2026

We see you there, dear reader, gazing silently up at the moon, heart aching to know the history of wistful, as if it could be divined on the lunar surface. And we'd like to ease your melancholy by telling you that the knowledge you seek—nay, pine for—is closer at hand. The word wistful comes from wistly, a now-obsolete word meaning "intently," and the similar-sounding wishful. Wistly, in turn, likely comes from whist, an old term meaning "silent." What's more certain is that our modern wistful is a great word to describe someone full of pensive yearning, or something inspiring such yearning.
