When you remember something, you are mindful of it. It's appropriate, therefore, that "commemorate" and other related memory-associated words (including "memorable," "memorial," "remember," and "memory" itself) come from the Latin root "memor," meaning "mindful." Some distant older relatives are Old English "gemimor" ("well-known"), Greek "mermēra" ("care"), and Sanskrit "smarati" ("he remembers"). English speakers have been marking the memory of important events with "commemorate" since the late 16th century.
