用法
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 to be often used to refer only 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
