Today, I learned something new about the phrase bold-faced lie. What I learned was that it's not a bold-faced lie, but a bald-faced lie. Being the stubborn individual that I am, especially when it comes to my command of the English language and my lexical arsenal, I did some digging into the origins of that phrase.
I found out that bold-faced lie is actually an acceptable modern variant. In this day and age, bold-face can refer to the boldness of type. Back then, this really had no meaning. The more surprising thing that I found out, however, was that bald-faced lie wasn't the original phrase. In fact, the earliest version of this was actually bare-faced lie. As you can imagine, this referred to being clean-shaven with nothing to hide. It follows that bald-faced grew from bare-faced. And, the rest is history.
So, we have a happy ending. I'm happy to know that I haven't been using a non-existent phrase. And, I'm just as happy to have learned of the phrase's evolution.
