To reminisce means to think or talk fondly about experiences from your past. When your grandmother reminisces about her childhood summers at the lake, she's remembering those days with pleasure and sharing the memories out loud. When old teammates reminisce about their championship season, they're reliving those exciting moments together through conversation.

The word carries a warm, nostalgic feeling. People don't usually reminisce about boring moments or things they'd rather forget. Instead, they reminisce about happy times, funny incidents, or meaningful experiences that shaped who they are. You might reminisce about your first day of kindergarten, a favorite family vacation, or the time your science experiment worked perfectly.

Reminiscing often happens naturally when something triggers a memory: looking through old photos, hearing a certain song, or visiting a place you haven't been in years. Friends might spend an afternoon reminiscing about elementary school adventures, laughing about things that seemed so important then. The act of reminiscing helps us appreciate how far we've come and remember the people and moments that mattered most along the way.
