## Origin

The word continues Middle English rewme, also spelled realme or reaume, borrowed from Old French reaume, realme ("kingdom"). Its deeper origin is unclear. The usual proposed source is Late or Vulgar Latin *rēgālimen, combining regimen with rēgālis. The present spelling became usual around 1600. The /l/ in today's pronunciation either arose through the spelling or developed under the influence of the word's etymology.
