Moves air, not temperature, and still manages to save your life in August.
means A motor-driven set of rotating blades that circulates air in a room to speed up evaporation and convection cooling, rather than actually lowering the air's temperature.
from 'Fan' traces back to Latin 'vannus,' a winnowing basket shaken to separate grain from chaff by moving air — so the word was already about stirring air long before electricity existed. 'Electric' comes from Greek 'elektron,' meaning amber, because ancient observers noticed rubbed amber could attract light objects, a curiosity that eventually grew into the whole science of electricity. The two words only married in the late 1800s, when small electric motors finally made spinning a fan blade easier than waving a basket by hand.
