Origin

mid 17th century: from Latin fortuitus, from forte 'by chance', from fors 'chance, luck'.

Usage

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. In modern uses, however, fortuitous tends more often to be used to refer to fortunate outcomes, and the word has become more or less a synonym for ‘lucky’ or ‘fortunate.’ This use is frowned upon as being not etymologically correct and is best avoided except in informal contexts.
