Background / Comments
I have heard or read this word, but I think it is misused to merely mean “hard to overcome” instead of the true meaning of “unable to be overcome”. As you might expect, our word came from Latin, where superare means “to go over, surmount, overcome, or excel”: with the addition of the prefix in- (not) and the suffix -abilis (able), we get insuperabilis, which was anglicized as our word.
