Unsinkability. Is that a real term? Well, I’m going to say yes, seeing how my spellcheck feature didn’t draw a red line under the word. But what does it really mean to be unsinkable? It’s not always a positive term, of course. The Titanic was said to be unsinkable, and that didn’t go so well. But in my lexicon, if I feel that someone is considered unsinkable, it’s high praise.
