Etymology: "Vibrates" is the third-person singular present of "vibrate," which comes from Latin "vibrare," meaning to move quickly to and fro, to brandish, or to quiver. The Latin verb is related to "vibrum," a rare word for a quivering motion, and the English verb was borrowed from that Latin root. The English verb took on its physical sense early, describing things that shake or tremble, and only later gained the meaning it carries in science, where it describes a body oscillating about a rest position. Over time the verb also came to describe emotional responses, as when a voice or a mood is said to vibrate with feeling.
