I wanted to join the hiking trip, but I'm unable to get off work this weekend.

That's a bummer! I was looking forward to having you there.

Root Explanation

**Unable** → It is formed from "un-" (meaning not) and "able" (from Latin *habilis*, meaning capable or fit). The word "unable" means not capable or not fit to do something.

Memory Tip

Think of 'not' ('un-') being added to 'capable' ('able') — that's why unable means not capable.
