The word "纪念馆" is formed from three characters: "纪" meaning to record or commemorate, "念" meaning to remember or cherish, and "馆" meaning a building or hall. The combination of "纪" and "念" creates the compound "纪念", which conveys the act of commemoration or remembrance. Adding "馆" specifies a physical structure, so the entire word denotes a memorial hall or museum built for the purpose of honoring and remembering a person or event.
