What does whirr mean?
Whirr is a word for a low, continuous humming or buzzing sound, especially the sound made by something spinning, rotating, vibrating, or operating mechanically. Used as a verb, it describes the production of that sound: a fan, propeller, engine, or printer might whirr during use. Used as a noun, whirr names the sound itself or refers to the mechanism producing it. The word is closely associated with machinery and fast-moving mechanical parts, but it can also describe softer sounds from electric appliances, insects, or rapid movement. Although it may suggest that something is working efficiently, it can carry a faintly ominous or suspenseful implication when applied to unfamiliar machinery in a story. Whirr is especially useful when the sound is a recurring background feature or an important clue to someone or something nearby. The related spelling “whir” is also widely accepted.

Where does whirr come from?
Whirr is an imitative word whose sound echoes the low noise made by rapidly rotating or vibrating objects. It entered English in the early 17th century, during a period when several English words for mechanical sounds were coined on this principle. The related spelling “whir” became established as an alternative form, while the extended participle “whirring” follows the usual English formation of a verb ending in a consonant.
