What does depositary mean?
A depositary is a person, bank, or other institution to which something — money, securities, documents, or valuables — is entrusted for safekeeping. The word carries a strong implication of trust and legal responsibility: a depositary does not merely store items but assumes a duty of care toward them. In international law, a depositary government or organization keeps the original text of a treaty and receives official notifications from signatory states. In finance, depositary banks hold shares on behalf of investors and issue instruments such as American and Global Depositary Receipts, enabling cross-border trading of foreign stocks. The term derives from the Latin deponere, meaning to put down or lay aside, entered English in the sixteenth century via Medieval Latin depositarius, and is closely related to depository, which refers more specifically to a physical storage place. Formal in tone, depositary appears most often in legal contracts, banking regulations, and diplomatic texts rather than casual conversation.
nounA depositary is a person or institution with whom something is deposited or entrusted for safekeeping, especially securities or other valuable assets. It also denotes a place where things are stored.
- A person or institution entrusted with the safekeeping of funds, securities, or documents, often with fiduciary responsibilities (e.g. a depositary bank).
- A state or organization designated to keep and safeguard an official document, such as an international treaty, and its instruments of ratification.
- A storehouse or place where goods are deposited (a sense now largely merged with 'depository').
"The treaty named the United Nations as its depositary, responsible for holding the original signed documents."
"The global depositary receipts were issued through a London-based depositary bank, allowing overseas investors to trade the shares easily."
"France was appointed depositary of the agreement, charged with receiving each country's formal notification of ratification."
The standard plural follows the regular -y to -ies pattern. The singular form remains far more common in practice.
"The regulation applies to all depositaries operating within the European Union."
When countries sign a major international treaty, one nation is chosen as the 'depositary' — literally trusted to keep the world's paperwork safe.

Etymology of depositary
Depositary comes from the Latin verb deponere, meaning 'to put down, lay aside', combined with the suffix -arius denoting a person connected with something. It passed into English in the sixteenth century through Medieval Latin depositarius, meaning a person with whom something is placed for keeping. Its sibling word depository arose around the same period from the same Latin source, and the two have remained close companions ever since, though depositary retains the stronger sense of personal or institutional trusteeship. Other relatives sharing the same Latin root include deposition, depot (via French dépôt), and deposit itself.
