Etymology: "Exchangeably" is a straightforward formation: the adjective "exchangeable," meaning capable of being exchanged or substituted for another, with the adverbial ending "-ly" attached to express the manner in which something is done. So "exchangeably" describes things done as equal substitutes, one standing in for the other without any difference in effect. The adjective "exchangeable" itself is built on "exchange," which came into English from Anglo-Norman and Old French "eschange," a noun tied to the verb "eschangier," meaning to barter or swap. The "-able" ending, borrowed from French and ultimately from Latin "-abilis," marks something that can be done. Put together, "exchangeable" means that a thing can be swapped, and the adverb reports that the swapping is done in that manner.
