Conversation

Have you heard about the project that was canceled due to its inviability?

Yeah, I read about that; it seemed like a bad idea from the start.

It's a shame because they put a lot of effort into it, despite the inviability.

True, but sometimes it's better to cut losses early than to keep wasting resources.

Root Explanation
Inviability → It is formed from "in-" (meaning not) and "viability" (from Latin "vita" meaning life, combined with the suffix "-able" meaning capable of). The word "inviability" means the state of not being capable of sustaining life or existence.
Memory Tip
Think of 'not' ('in-') being combined with 'capable of life' ('viability') — that's why inviability means not capable of sustaining life.
