A slip of the pen was first reported to be used in the 1650s by a British man. He’d written a letter professing his unending love for Lady Catherine, his love interest. On opening the letter, she saw that he’d signed off the letter with the words “Within Love” instead of “With Love.” When Lady Catherine related this to him days later, he’d laughed and said, “Oh, it was just a slip of the pen.” Those around loved the expression and it caught on, and years later, around 1725, its sister phrase a slip of the tongue began to become more popular, as people also made mistakes while speaking not just while writing.
