surcharge
UK: /ˈsɜːtʃɑːdʒ/ | US: /ˈsɜːrtʃɑːrdʒ/
n. an additional charge or payment
vt. to impose an extra fee or cost
The word "surcharge" originates from Old French surcharger, combining sur- (meaning "over" or "above," from Latin super-) and charger (meaning "to load" or "to impose a fee," from Late Latin carricare). The term evolved in Middle English to denote an extra burden or cost, reflecting its literal sense of "overloading" a base charge. The morpheme sur- is common in financial and legal contexts (e.g., surtax), while charge retains its dual meaning of physical burden and monetary demand.
