Here are some examples:
* "Elevator": One who elevates or raises something.
* "Translator": One who translates from one language to another.
* "Navigator": One who navigates or guides a ship or aircraft.
* "Operator": One who operates or works a machine.
* "Iterator": In computer programming, a special object that allows you to iterate through a sequence of items.
It's important to note that "-itor" is not always used to denote a person. It can also describe a process or thing, like "generator" (something that generates) or "depositor" (a place where something is deposited).
