Etymology

Origin of prefect

First recorded in 1300–50; Middle English, from Latin praefectus “overseer, director” (noun use of past participle of praeficere “to make prior,” i.e., “put in charge”), equivalent to prae- “before, prior to” ( see pre-) + -fectus (combining form of factus, past participle of facere “to make, do” ( see do ¹); see fact

Explanation

A prefect is a chief officer or magistrate, originally in ancient Rome. Like a mayor or governor, a prefect is someone powerful: a chief officer or chief magistrate. In ancient Rome, a prefect was not only in charge of a city or province but of the military too, just as the United States President is the military commander-in-chief too. The term prefect is a little old-fashioned, but there are still prefects around today.
