A person or institution that facilitates or conducts exchanges; someone who trades goods or currency.
From 'exchange' + -er (agent suffix). The -er suffix indicates the person or thing performing the action of the root verb.
Money changers (exchangers) were among history's most important and dangerous professionals—they controlled currency valuations at borders and trade routes, wielding economic power that sometimes rivaled kings, which is why they appear so frequently in medieval literature as both heroes and villains.
Agent noun '-er' carries historical masculine default; 'exchanger' assumes male actor in financial/trade roles despite women's documented exchange commerce roles.
Use 'exchange service,' 'exchange mechanism,' or 'exchange agent' to describe function without gendered assumptions.
["exchange service","exchange mechanism","exchange operator"]
Women have been traders, merchants, and currency exchangers historically; masculine-coded agent nouns erase documented economic agency.
