From Serendip (“variant of Serendib: Ceylon, Sri Lanka”) + -ity. Coined by English writer and politician Horace Walpole in 1754 based on the Persian story of The Three Princes of Serendip, who (Walpole wrote to a friend) were “always making discoveries, by accidents and sagacity, of things which they were not in quest of”.
