Lapsus calami is a noun that refers to a slip of the pen.

Our word of the day comes directly from a Latin phrase that translates into “slip of the pen.’ It is used to describe any mistake made in writing.

In my movie debut I played a character named Jeb in an old west thriller. But thanks to a lapsus calami, my character’s name was listed in the credits as Jen. I hope I don’t have any more slips of the pen like that. It would be nice for my parents to fully understand who I was playing in a movie.
