early 13c., “to load, put a burden on or in; fill with something to be retained,” from Old French chargier “to load, burden, weigh down,” from Late Latin carricare “to load a wagon or cart,” from Latin carrus “two-wheeled wagon” (see car).
Senses of “entrust,” “command,” and “accuse” all emerged in Middle English and were found in Old French. Sense of “rush in to attack, bear down upon” is from 1560s, perhaps through earlier meaning “load a weapon” (1540s). Meaning “impose a burden of expense” is from mid-14c. That of “to fix or ask as a price” is from 1787; meaning “hold liable for payment, enter a debt against” is by 1889. Meaning “fill with electricity” is from 1748. Related: Charged; charging.
