black mark

The term black mark refers to a lasting indication of failure, misconduct, or disgrace on a person's record or reputation. It implies a blemish that is difficult to remove and may hinder future opportunities. The idiom likely originates from the historical use of black balls or stones to vote against candidates for club membership (see blackball), or the literal practice in 19th-century schools and military units of marking a register with a black cross or dot to denote bad behavior.

Perspectives on the term vary based on views regarding linguistic sensitivity and racial connotations. Critics of the term argue that it reinforces a metaphorical dualism in the English language where "black" equates to bad, wrong, or dirty, while "white" equates to good or pure. They suggest that replacing such idioms helps eliminate unconscious bias and anti-Black sentiment. Conversely, many speakers view the phrase as a neutral descriptor derived from ink color or voting tokens rather than skin color, arguing that it lacks racial intent and that removing it ignores its specific historical context.

Example:
"The disciplinary hearing resulted in a permanent black mark on the officer's service record."

Example:
"She worried that the failed project would be a black mark against her when applying for the promotion."
