Root Explanation

Defocus → It is formed from "de-" (meaning down or away) and "focus" (from Latin "focus", meaning hearth or center). The word "defocus" means to move away from the center of focus or to blur an image.

Memory Tip

Think of moving something 'away' ('de-') from its 'center' ('focus') — that's why defocus means to blur or lose clarity.
