A commemoration is a ceremony, event, or object that honors and helps people remember an important person, event, or achievement from the past. When a town holds a commemoration of its founding, residents might gather for speeches, parades, or special programs that celebrate how their community began. When a school dedicates a plaque in commemoration of a beloved teacher, they're creating something permanent to keep that person's memory alive.

A memorial statue is a form of commemoration. Memorial Day commemorates soldiers who died serving their country. A moment of silence can commemorate a tragic event. Even a special anniversary dinner commemorates something meaningful, like grandparents celebrating fifty years of marriage.

Commemoration differs from simply remembering privately. When you commemorate something, you mark it publicly and formally, often with others. You might remember your grandmother's birthday quietly, but a family reunion in her honor would be a commemoration. The act of commemorating says, “This matters enough that we should pause, gather together, and make sure we don't forget.”
