The Religious History of Incumbent

When incumbent was first used in English in the 15th century, it referred to someone who occupied a benefice—a paid position in a church. This was often a lifetime appointment; the person could only be forced to leave the office in the case of certain specific legal conflicts. In the mid-17th century, incumbent came to refer to anyone holding any office, including elected positions. In the modern American political system, incumbent typically refers to someone who is the current holder of a position during an election for that position. The word also functions as an adjective with its most common meanings being "occupying a specified office" ("the incumbent mayor") and "obligatory" ("it is incumbent upon us to help"). Incumbent came to English through Anglo-French and derives from the Latin incumbere, meaning "to lie down on."
