“ CHARGE (through the Fr. from the Late Lat. carricare, to load in a carrus or wagon; cf. “cargo”) , a load; from this, its primary meaning, also seen in the word “charger,” a large dish, come the uses of the word for the powder and shot to load a firearm, the accumulation of electricity in a battery, the necessary quantity of dynamite or other explosive in blasting, and a device borne on an escutcheon in heraldry. “Charge” can thus mean a burden, and so a care or duty laid upon one, as in “to be in charge” of another. ”
