Did you know?

When you remember something, you are mindful of it. And you are especially mindful when you commemorate something, formalizing your remembrance by doing something special, such as attending a parade or taking part in a ceremony. 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.” English speakers have been marking the memory of important events with commemorate since the late 16th century.
