The history of the world is peopledwith dauntless men and women who refused to be subdued or “tamed” by fear. The word dauntless can be traced back to Latin domare, meaning “to tame” or “to subdue.” When our verb daunt (a domaredescendant borrowed by way of Anglo-French) was first used in the 14th century, it shared thesemeanings. The now-obsolete “tame” sense referred to the taming or breaking of wild animals, particularlyhorses: an undaunted horse was an unbroken horse. Not until the late16th century did we use undauntedwith the meaning “undiscouragedand courageously resolute” to describe people. By then, suchlionhearted souls could also be described as undauntable, and finally, in Henry VI, Part 3, Shakespeare gave us dauntless.
