The Origin of Flier or Flyer
The word comes from the verb “to fly,” which entered English from Old English flēogan. When nouns were formed, two spellings appeared: flier and flyer.
- Flier follows traditional English spelling rules (like crier from cry).
- Flyer developed later and became popular due to printing, advertising, and American English influence.
Over time, flyer gained dominance in marketing and aviation, while flier remained common in formal and traditional writing. That’s why both spellings still exist today.
