reservationist

The word 'reservationist' is built upon the core Latin verb reservare, meaning "to keep back" or "to save." The addition of the noun-forming suffix '-ation' creates 'reservation,' which denotes the act of keeping something back or, in modern commercial contexts, the arrangement to have something held for future use. Finally, the agent suffix '-ist' is appended, a productive suffix in English borrowed via Latin from Greek '-istes,' to specify a person who performs the action. Thus, the literal morpheme chain "one who performs the action of keeping back" evolved into the modern professional and ideological senses, referring respectively to a person who secures bookings or a person who holds a cautious position.
