Usage of Fortuitous

Sense 2a has been influenced in meaning by fortunate. It has been in standard if not elevated use for some 70 years, but is still disdained by some critics. Sense 2b, a blend of senses 1 and 2a, is virtually unnoticed by the critics. Sense 1 is the only sense commonly used in negative constructions.

Did You Know?

For some 250 years, until the early part of the 20th century, "fortuitous" meant one thing only: "happening by chance." This was no accident; its Latin forebear, fortuitus, derives from the same ancient root as the Latin word for "chance," which is "fors." But the fact that "fortuitous" sounds like a blend of "fortunate" and "felicitous" (meaning "happily suited to an occasion") may have been what ultimately led to a second meaning: "fortunate." That use has been disparaged by critics, but it is now well established. Perhaps the seeds of the newer sense were planted by earlier writers applying overtones of good fortune to something that is a chance occurrence. In fact, today we quite often apply "fortuitous" to something that is a chance occurrence but has a favorable result.
