Root Explanation

Inoculum → It is formed from "in-" (meaning into) and "oculus" (meaning eye). The term originally referred to something introduced into the body, akin to how an eye can be a point of entry or observation, particularly in the context of introducing a substance for immunization.

Memory Tip

Think of something being introduced 'into' ('in-') the 'eye' ('oculus') of the body, which helps you remember that an inoculum is a substance introduced for immunization.
