Etymology: "Fiduciary" comes from the Latin "fiduciarius," meaning "held in trust," which itself grows from "fiducia," the Latin word for "trust" or "confidence." The root "fides," meaning "faith," sits behind both, so a fiduciary is literally someone whose position rests on faith placed in them. In Roman law, the idea was concrete. A "fiducia" was an arrangement in which property was transferred to someone on the understanding that it would be held and returned under agreed terms, so the legal weight of the word lay in the relationship of trust itself rather than in the object handed over. That is why the word still carries the sense of a person entrusted with another's money or property and bound to act in that person's interest. In modern English, the word is used mainly as a noun for someone who manages assets for others, and as an adjective describing the duties that go with that role. The meaning has stayed close to its Latin origin: the core of the word is still the obligation of trust.
