Root Explanation

Soundly → It is formed from "sound" (from Old English *sund*, meaning healthy or safe) and the suffix "-ly" (meaning in a manner of). The word "soundly" means in a manner that is healthy or secure, often used to describe deep or undisturbed sleep.

Memory Tip

Think of being in a 'healthy' state ('sound') and doing something 'in that manner' ('-ly'). This helps you remember that 'soundly' means doing something in a secure or deep way.
