Did you know?

Fortune favors the bold—or, as ancient Romans are known to have said, “audentes Fortuna iuvat.” Audentes here is the present participle of the Latin verb audēre, meaning “to dare,” a word that also led, via several etymological twists and turns through the centuries, to the English adjective audacious. When it first appeared in English in the mid-1500s, audacious meant “intrepidly daring,” a sense we still use today when we apply the word to various feats of derring-do and those who dare to do them. Since then it has developed several additional meanings, including the closely related “recklessly bold” and “marked by originality and verve,” as in “her audacious new album heralds the future of hip-hop.” Of course, with audacity (another audēre descendent) comes risk that fortune, despite the maxim, doesn’t always favor: as fungi foragers know, there are sagacious mushroomers, and audacious mushroomers, but there are no sagacious audacious mushroomers.
