Did you know?

Humanum est errare” is a Latin expression that translates as “To err is human.” Of course, cynics might say that it is also human to deceive. The history of the word fallible simultaneously recognizes both of these character flaws. In modern usage, fallible refers to one’s ability to make mistakes, but it descends from the Latin verb fallere, which means “to deceive.” Fallible has been used to describe the potential for error since at least the 15th century. Other descendants of fallere in English, all of which actually predate fallible, include fallacy (the earliest, now obsolete, meaning was “guile, trickery”), fault, false, and even fjail. Whoops, we mean fail.
