Did you know?

Before its meaning expanded, fortuitous meant one thing only: “happening by chance.” This was no accident; its Latin forebear, fortuitus, shares the same ancient root as fors, the Latin word for “chance.” But the fact that fortuitous sounds like a blend of fortunate and felicitous (“happily suited to an occasion”) likely led to a second meaning of “fortunate, lucky,” with the seeds of the newer sense perhaps planted by writers applying overtones of good fortune to something that is a random occurrence. The “lucky” use has been disparaged by critics, but it is now well established. Irregardless (cough), employing this sense in sterner company may be considered chancy.
