Etymology
The word "overcharge" is a transparent compound formed within Middle English by combining the native prefix "over-" with the verb "charge," borrowed from Old French. The prefix "over-" carries its enduring sense of excess or beyond a limit. The core verb "charge" originates from the Latin concept of loading a wagon (carrus), which semantically broadened to encompass imposing a burden, a duty, or a financial cost. Therefore, the literal construction "to load excessively" or "to burden beyond measure" logically evolved into its modern primary meanings: to impose an unfairly high price or to put too much electrical energy into a device.
