I heard you were feeling a bit under the weather last week.

Yeah, I had a subacute cough that wouldn't go away.

That sounds frustrating! Is it getting any better now?

It is, thankfully! The doctor said it was just a mild infection.

Root Explanation

Subacute → It is formed from "sub-" (meaning under or below) and "acutus" (meaning sharp or severe). The word describes a condition that is less severe than acute but still significant, indicating a state that is under the full intensity of an acute condition.

Memory Tip

Think of something that is 'under' ('sub-') the full 'sharpness' or severity ('acutus') of a condition — that's why subacute refers to a less severe state.
