Etymology
Origin of administrator
First recorded in 1400–50; late Middle English, from Middle French administratour, from Latin administrātor, equivalent to administrā(re) “to assist, serve” ( see administer) + -tor -tor
Explanation
The boss, the head honcho, the person in charge: An administrator is the person responsible for managing things and running the show. Administrators are often found directing government agencies, organizing institutions, or leading school departments. They're the decision makers and the planners, the people who put in place or administer the rules and guidelines. In other words, the administrator's office is probably the last place you want to end up if you're in trouble.
