Roots and History

The exact origins of the idiom "live wire" are uncertain, but it is believed to have originated in the late 19th or early 20th century. One theory suggests that it comes from the name of a type of electrical wire that was used to power early electric lights and appliances. These wires were known for being highly energized and always on the go, much like the people who are referred to as "live wires" today.
