the.com/ceiling fan
A room's way of redistributing hot air without actually cooling anything.
means A fan mounted on the ceiling that circulates air in a room by spinning blades, creating a breeze that makes you feel cooler even though the air temperature stays the same.
from Both halves are plain English: 'ceiling,' from Latin caelum (sky, heaven) by way of French, originally meant the lining or covering overhead before it settled on the specific sense of a room's upper surface; 'fan' traces back to Latin vannus, a winnowing basket used to toss grain into the wind to separate the chaff. Electric ceiling fans themselves are a late-19th-century invention, arriving alongside household electricity as a direct swap for hand-pulled punkah fans and hanging paddle fans that servants once worked by rope in hot climates.
