What term describes the act of honoring someone's memory through a ceremony?

The term that describes the act of honoring someone's memory through a ceremony is "commemorate." This verb specifically refers to the action of remembering and honoring an individual or event, often through various forms of ceremonies, memorials, or tributes. Commemorating serves to keep the memory of a person alive, celebrate their life, and reflect on the impact they had during their time. Events like memorial services, anniversaries, and even monuments can all serve as ways to commemorate someone significant.

The other terms do not fit this context: "condense" refers to making something denser or more compact, "concur" means to agree, and "console" involves providing comfort to someone, particularly in times of grief or distress, but none convey the act of honoring memory in a ceremonial context.
