proxy
This term centers on the concept of substitution, where one entity stands in for another to perform a function or provide information. In legal and corporate settings, it carries a formal, authoritative tone, implying a transfer of power or agency from a principal to a representative. In technical and scientific contexts, the word shifts toward a functional or indirect relationship. In computing, it describes a gateway that masks the identity of the original requester, while in science, it refers to an indirect measurement used to infer data about a system that is otherwise inaccessible.
