entrust

This verb conveys a high degree of confidence and a transfer of guardianship or authority. It is more formal than give or leave, implying a moral or professional obligation to protect what has been handed over. The emotional weight of the word suggests a vulnerability on the part of the giver and a solemn duty on the part of the receiver.

Usage depends heavily on the prepositional structure. When using to, the focus is on the object being transferred (the trust). When using with, the focus shifts to the person being empowered or burdened with the responsibility. This distinction allows speakers to emphasize either the value of the asset or the capability of the agent.
