finance: [14] Finance comes ultimately from Latin fīnis ‘end’, and its present-day monetary connotations derive from the notion of ‘finally settling a debt by payment’. Its immediate source is Old French finance, a derivative of the verb finer ‘end, settle’, which when it was originally acquired by English still meant literally ‘end’: ‘God, that all things did make of nought … puttest each creature to his finance’, Coventry Mystery Plays 1400. The debt-settling sense had already developed by that time, but this did not broaden out into the current ‘management of monetary resources’ until the 18th century.

finance (n.)youdaoicibaDictYouDict
c. 1400, "an end, settlement, retribution," from Old French finance "end, ending; pardon, remission; payment, expense; settlement of a debt" (13c.), noun of action from finer "to end, settle a dispute or debt," from fin (see fine (n.)). Compare Medieval Latin finis "a payment in settlement, fine or tax."

The notion is of "ending" (by satisfying) something that is due (compare Greek telos "end;" plural tele "services due, dues exacted by the state, financial means"). The French senses gradually were brought into English: "ransom" (mid-15c.), "taxation" (late 15c.); the sense of "management of money, science of monetary business" first recorded in English 1770.
