2. The characteristic of creating a strong emotional or intellectual connection that endures ; the physical process where an object vibrates more intensely at a certain frequency
3. The ability to generate a meaningful or prolonged impression on feelings or thoughts ; the condition in which a system oscillates with increased amplitude when subjected to a matching frequency

Etymology: The Latin verb "resonare" meant "to resound" or "to echo back," built from "re-" (back, again) and "sonare" (to sound). Its derived noun "resonantia" meant "echo," so the original sense was literal: a sound returning off a wall or hollow space. Old French took the idea over as "resonance," and English borrowed it from there, keeping that sense of sound bouncing back. The shift from echo to emotion happened gradually. Once people understood that a body such as a violin or a bell could amplify a sound that matched its own vibration, "resonance" came to name that physical sympathy between frequencies. From there the metaphor widened: a speech or a piece of music could strike a listener as if it found a matching chord inside them, and the word moved from acoustics into talk of feelings and meaning.
