The etymology of the phrase "black mark" can be traced back to the Middle Ages. In those times, people used a quill and ink to write, and a mistake or error in writing was typically marked with a stroke or blot of ink. Because ink was usually black, such marks became known as "black marks". Over time, the term expanded beyond its literal meaning and came to represent any kind of negative mark or stain on someone's reputation or record. It is now commonly used to refer to a negative evaluation or criticism of someone's actions or behavior.
