Definition
A flyer is the same as a flier: a single-sheet advertisement or notice, used to promote an event, product, or service. Think of it as a paper-based pop-up ad. Flyers are meant to be attention-grabbing and quickly convey essential information. They are like a quick shout in a crowded place. It's the same as a 'flier,' just with a different spelling, and no real difference in meaning.
