What is the word most opposite in meaning to "commemorate"?

The word "commemorate" means to honor or remember someone or something, typically through a ceremony or act of remembrance. Therefore, the most opposite in meaning to "commemorate" would be "neglect." When one neglects something, it implies a lack of attention or acknowledgment, which directly contrasts with the concept of commemorating, where there is an intentional act of remembrance or celebration of significance. Neglecting something means disregarding its importance, while commemorating highlights it.

The other options don’t serve as opposites in this context. "Celebrate" involves honoring an occasion or event, which is in line with commemorating. "Resuscitate" refers to bringing something back to life or consciousness, typically used in medical contexts, and does not relate to remembrance. "Ameliorate" means to make something better or improve a situation, which also does not connect directly to the idea of honoring or remembering. Thus, "neglect" stands as the most appropriate opposite to "commemorate."
