Etymology

From Latin incumbentem + English -ent (suffix denoting the causing, doing, or promoting of an action). Incumbentem is the accusative singular of incumbēns (“reclining”), the present active participle of incumbō (“to lay upon, to lean or recline on; to fall upon, to press down on”), from in- (prefix meaning ‘against; into; on, upon’) + cumbō (“to lie down, recline”) (ultimately from Proto-Indo-European ḱewb-).

From Middle English incumbent, encumbent (“holder of an ecclesiastical benefice, dean, parson, etc.; cleric (?)”), from Medieval Latin incumbēns (“holder of a church position”) + Middle English -ent (suffix denoting one that causes, does, or promotes an action). Incumbēns is derived from Medieval Latin incumbō (“to obtain; to possess”), from Latin incumbō (“to lay upon, to lean or recline on; to fall upon, to press down on”): see etymology 1.
