Termini refers to the plural form of "terminus," which is a point of reference or an endpoint in various contexts. In transportation, it often denotes the final station or stop on a route, such as a bus or train line. For example, the Termini station in Rome serves as a major hub for both local and international travel. In a broader sense, termini can also relate to the limits or boundaries of a concept, project, or process. In fields like linguistics or philosophy, it may refer to the defined endpoints of a discussion or argument, helping to clarify the scope of analysis.
