What does it mean to commemorate?

To commemorate means to honor the memory of someone or something, typically through a special act or ceremony. This can involve gathering with others to recall and pay tribute to events, individuals, or significant moments in history. Commemoration is often seen in practices such as memorial services, monuments, or annual observances that serve to keep the memory alive and recognize its importance.

In contrast, the other choices refer to different concepts. Celebrating a holiday or event involves festivities and joy, while ignoring a situation suggests a lack of attention or acknowledgment. Planning for the future concerns preparation and foresight, which is distinct from the act of honoring memories or past events. Thus, honoring the memory of something or someone is the essence of commemoration.
