fortuitous

fort(chance)-u-itous   [itous = ity-ous]

adj.偶然的 [Happening by accident or chance]

adj.幸運的 [lucky; fortunate]

ps.1

fortune n.幸運 n.財富

1250–1300; ME < OF < L fortūna chance, luck, fortune, deriv. of fort- (s. of fors) chance

fortune 來自拉丁的 fortūna，其中fort就是"chance"的意思

ps.2

Usage Note: In its best-established sense, fortuitous means "happening by accident or chance." Thus, a fortuitous meeting may have either fortunate or unfortunate consequences. For decades, however, the word has often been used in reference to happy accidents.

 fortuitous最好的釋義是"偶然的"，因此fortuitous可以指"幸運的"也可指"不幸運的"，不過今日大家都常用來指"幸運的"

ps.1

fosse字源："ditch, trench," 1440, from O.Fr. fosse, from L. fossa "ditch," in full fossa terra, lit. "dug earth," from fem. pp. of fodere "to dig"

fosse的"foss"在拉丁文中指的是"dig挖"的意思，所以fosse指ditch溝
