What the hell is UNFORTUITOUS supposed to mean?! Fortunate is not synonymous with fortuitous, not in the context that we are discussing it anyway, so putting an un- to fortuitous does not make the word mean “unfortunate”. Fortunate means unexpected good luck while fortuitous means happening by chance or it is something unforeseen. So while coup d’etat or typhoons or the likes are by no means unfortunate events, they are not "unfortuitous" events. Get it? GET IT?
