"Governor" and "gubernatorial" may not look as if they're related, but they are. The root of both was the Greek verb "kuberetes," meaning "helmsman of a ship," or, more metaphorically, "ruler." The Latin descendant of "kubernetes" was "gubernare," meaning "to rule," which gave us the English word "gubernator" (no kidding) around 1522, meaning "ruler." The adjective "gubernatorial," which appeared around 1734, at first meant "pertaining to a ruler or governor" in the generic sense of "governor," but today is almost always only used in reference to state officials bearing the formal title "Governor."
Now, if we back up a moment to that Latin word "gubernare," we find that it was also filtered through Old French to produce the word "governeur," meaning "ruler," which gave us the English word "governor" in the 14th century. So "governor" and "gubernatorial" are indeed very closely related.
Incidentally, the French also used the Greek "kubernetes" (ruler) to produce the word "cybernetique," meaning "the art of governing." In the late 1940s, the American mathematician Norbert Weiner appropriated and Anglicized "cybernetique" as "cybernetics" to describe his theory of communications. Writer William Gibson then modified Weiner's term in his 1984 science fiction novel "Neuromancer," coining everyone's least-favorite buzz-word, "cyberspace."
