Etymology: The English noun "ambulator" was borrowed directly from Latin "ambulātor", a walker or one who walks about. That Latin word is built from "ambulāre", to walk, which combines the prefix "ambi-", meaning around or about, with "alō", a verb for moving or going, and the ending "-tor", which marks a person or thing that performs an action. So the core idea is literally a going-around, the same motion we still hear in "perambulate" and "ambulance." The word's meaning in English stayed close to that original sense of a person who walks, and only later narrowed to the modern device: a frame or support that a person leans on while learning to walk or recovering from injury. Its literal roots survive in the familiar word "ambulance," which comes from the same Latin verb and was once a mobile field hospital that moved with an army.
