Have you ever thought about the impossibility of flying without any help?

Yeah, it sounds crazy, but it would be amazing if we could!

Right? I mean, the idea of just soaring through the sky feels like a dream, but it’s an impossibility for now.

True! But who knows what the future holds; maybe one day it won't be.

Root Explanation
Impossibility is formed from "in-" (meaning not) and "possibilis" (from Latin, meaning able to be done) and the suffix "-ity" (meaning the state or condition of). The word describes the state of being not able to be done or achieved.
Memory Tip
Think of 'not' ('in-') being combined with 'able to be done' ('possibilis') — that's why impossibility means the state of something that cannot be done.
