I feel like I've been so underactive lately.

Really? What do you think is causing it?

I don't know, maybe I need to find a new hobby to get moving again.

That sounds like a great idea! Something active could really help.

Root Explanation

Underactive → It is formed from "under-" (meaning below or insufficient) and "active" (from Latin "activus", meaning to do or to act). The word describes a state of being insufficiently active or not performing at a normal level of activity.

Memory Tip

Think of being 'below' ('under-') the normal level of 'doing' or 'acting' ('active') — that's why underactive means not active enough.
