A more formal or literary verb for entrusting something valuable or important to someone's care. Often used for hopes, dreams, or messages.

English 'entrust with' often becomes 'entrust X to someone' in Japanese. The pattern is usually 〜を（人）に＋verb. Avoid direct translations like 'entrust someone with something' using 任せる with a person as the direct object; it's ungrammatical.
悩みを打ち明ける相手がいない。
I have no one to confide my worries to.
