Root Explanation
Autofocus → It is formed from "auto-" (from Greek "αὐτός" meaning self) and "focus" (from Latin "focus" meaning hearth or center). The word "autofocus" refers to a camera feature that automatically adjusts the lens to focus on a subject by itself.
Memory Tip
Think of 'self' ('auto-') adjusting the 'center' ('focus') of a camera — that's how autofocus works.
