The word 委托 is formed through the logical combination of two constituent characters, each contributing a core meaning to create a new, compound concept. The first character, 委 (wěi), carries the inherent idea of "to assign" or "to entrust", suggesting the action of handing something over. It is paired with 托 (tuō), which means "to hold in the palm" or "to rely upon", imparting the sense of placing something into another's care with trust. Thus, the formation is conceptual: one part denotes the act of handing over a duty, and the other completes it with the act of receiving and bearing that responsibility, together perfectly encapsulating the meaning "to entrust".
