Why this word is great

WHIRR — [Noun/Verb] A sibilant buzz or vibration, especially from something in rapid motion; to make such a sound. From Middle English whirren, probably from early Scandinavian; compare Old Norse hvirfla (“to whirl, spread”), Danish hvirre, Norwegian kvirre. Unlike a "hum," which suggests a low, steady drone of contented machinery, or a "buzz," which implies a chaotic, insectile agitation, a whirr is the crisp, aerodynamic signature of contained, efficient velocity. It is the high, clean note of a film projector’s reel in a dark room, the taut, metallic purr of a fishing reel surrendering line, or the precise, spinning whisper of a dentist’s drill before it touches enamel. It is the audible hymn of a mechanism performing its singular purpose—a brief aria of function before the inevitable stillness.
