The traditional, etymological meaning of fortuitous is ‘happening by chance’: a fortuitous meeting is a chance meeting, which might turn out to be either a good thing or a bad thing. Today, however, fortuitous tends to be often used to refer only to fortunate outcomes and the word has become more or less a synonym for ‘lucky’ or ‘fortunate’ (the ball went into the goal by a fortuitous ricochet). Although this usage is now widespread, it is still regarded by some people as incorrect


Mid 17th century: from Latin fortuitus, from forte ‘by chance’, from fors ‘chance, luck’.
