Conversation

Have you ever thought about the idea of invincibleness?

Yeah, it sounds pretty cool, but is it really possible?

I guess it's more of a mindset than an actual state of being.

True, believing in your own invincibleness can really boost your confidence.

Root Explanation
Invincibleness is formed from "in-" (meaning not), "vincere" (meaning to conquer), and "-ness" (meaning the state of being). The word describes the state of being not conquerable or unbeatable.
Memory Tip
Think of 'not' ('in-') being able to 'conquer' ('vincere') — that's why invincibleness means the state of being unbeatable.
