hitchhiker

the word 'hitchhiker' is a 20th-century american english compound. its first element, 'hitch', carries the dual historical senses of moving with a jerk and temporarily fastening or connecting something. the second element, 'hike', in its dialectal use, meant to travel on foot or to pull up, as in lifting oneself into a vehicle. the combined form 'hitchhike' thus vividly evokes the action of jerking one's thumb to signal a driver and then pulling oneself into the vehicle for a temporary, free ride. the agent suffix '-er' is then added to denote the person performing this action, creating a term that perfectly encapsulates the informal and improvisational nature of this mode of travel.
