I heard the weather is going to be unstabler this week.

Really? That sounds a bit worrying.

Root Explanation

Unstabler → It is formed from "un-" (meaning not) and "stable" (from Latin "stabilis", meaning firm or steady) and "-er" (meaning a person who). The word "unstabler" refers to a person or thing that is not stable or causes instability.

Memory Tip

Think of 'not' ('un-') being added to 'stable' — this helps you remember that 'unstabler' means something or someone that is not steady.
