vibration
UK: vaɪˈbreɪʃən | US: vaɪˈbreɪʃən
n. a rapid back-and-forth movement of a physical object or medium
n. (physics) an oscillation of a system about an equilibrium position
n. (figurative) a palpable emotional or energetic resonance
Derived from Latin vibratio ("a shaking, brandishing"), from vibratus, the past participle of vibrare ("to vibrate, tremble"). The root vibr- conveys rapid motion, echoed in related words like vibrant (energetic) and vibrato (musical technique). The suffix -ion nominalizes the action, solidifying its modern usage in physics (mechanical oscillations) and abstract contexts (emotional "vibes").
