Have you ever noticed how some people seem invisible in a crowd?

Yeah, it's strange how some just blend in so well.

I wonder if it's something about their style or attitude that makes them feel invisible.

Maybe! Or they're just really good at being low-key.

Root Explanation
Invisible → It is formed from "in-" (meaning not) and "visibilis" (from Latin, meaning able to be seen). The word "invisible" means not able to be seen.
Memory Tip
Think of 'not' ('in-') being combined with 'able to be seen' ('visibilis') — that's why invisible means something that cannot be seen.
