What does trustee mean?
A trustee is a person or organization entrusted with administering property, money, or other assets for the benefit of someone else under a legal trust. Trustees owe their beneficiaries duties of care and loyalty: they must manage the entrusted assets prudently, avoid conflicts of interest, and act in the beneficiaries’ interests. The word also has an important institutional use, as in the board of trustees of a charity, foundation, university, or pension scheme, whose members share responsibility for governance and stewardship. In this setting, trustee suggests impartial oversight rather than direct day-to-day ownership. The verb “trustee” is rare but occurs in legal English, especially where property is placed in someone else’s trust. Because the role carries fiduciary responsibility, a trustee cannot treat entrusted assets as personal property. The term is consequently formal and legally precise, and it is related to, but not synonymous with, a beneficiary, who receives a benefit, or a trustor, who creates the trust. “Trustee” is useful when the emphasis is on faithful stewardship of something entrusted to another’s care.
A person or body legally appointed to administer property or assets for the benefit of another, or a member of an organization entrusted with governing it.
"She was appointed trustee of the family’s charitable trust."
The institutional sense is especially common in phrases such as “board of trustees.”
To appoint someone as a trustee or entrust property to someone to administer as trustee.
"The parties agreed to trustee the property pending settlement."
This is a rare, chiefly legal use and is less common than the noun.
The regular plural refers to people serving as trustees, whether individually or collectively as a board.
"The trustees met to review the charity’s annual budget."
A trustee is trusted with what is not theirs—faithful stewardship without personal ownership.

Where does trustee come from?
The word was borrowed from Old French trustee, meaning “a trusted person,” ultimately from Latin trusting, the present participle of trusting. It entered English in the late Middle English period and initially conveyed the idea of someone in whom another could place confidence; its legal sense developed alongside the doctrine of trusts. The modern verb reflects the same transfer of responsibility, while related English forms include trust, entrust, trustworthy, and trusteeship.
