Keynoter → It is formed from "key" (from Old English *cæg*, meaning a device for opening) and "-noter" (derived from "note" which comes from Latin *nota*, meaning a mark or sign). The word "keynoter" refers to a person who delivers a keynote address, marking the main theme or important points of an event.
Think of a 'key' as something that opens or reveals important ideas, and a 'noter' as someone who highlights or marks those ideas. This helps you remember that a keynoter is someone who presents the main themes.
