What does terminus mean?
A terminus is the endpoint or final stopping place of a route, most recognizably the end station of a train or bus service. It can also refer to the boundary of a geographical area, the extreme point of a journey, or the conclusion and limit of a process or period. In transport contexts, the word is precise and neutral: a terminus identifies the place where a service ends, whereas a station may also be an intermediate stop. Figuratively, reaching a terminus implies that something has reached its final stage or limit. The word is especially common in formal writing about railways, bus networks, roads, infrastructure, planning, and organized processes. It also appears in literary language when describing the endpoint of a journey through life, time, or experience. Derived from Latin, where terminus meant a boundary or end, it retains a clear sense of finality while remaining useful whenever the precise endpoint of a route or undertaking needs to be identified.

Where does terminus come from?
Terminus entered English from Latin terminus, a noun meaning “boundary,” “end,” or “limit,” used for a boundary point and especially for the end of a route. The English word dates from the early modern period and initially conveyed the idea of a boundary or terminal point. Latin terminus is related to terminare, “to set a limit or end,” and to a family of English words including determine, determination, and exterminate.
