Root Explanation

Surrogate → It is formed from "sur-" (meaning over or above) and "rogare" (meaning to ask or to propose). The word originally referred to someone who is appointed to act on behalf of another, thus implying a role that is above or in place of the original.

Memory Tip

Think of someone who is 'acting on behalf of' another person — 'sur-' means over or above, and 'rogare' means to ask, which helps you remember that a surrogate is someone who takes the place of another.
