Associated Press: Journalists should avoid the word 'mistress,' use 'companion' or 'lover' instead

The Associated Press on Friday said that journalists will now be urged to avoid using the term "mistress" to describe a woman in an illicit relationship with a married man, suggesting that writers opt for the more neutral terms "companion" or "lover." 

In a tweet on Friday morning, the AP Stylebook, long the standard-bearer of basic journalistic style in the United States, announced the language usage change. 

"We now say not to use the archaic and sexist term 'mistress' for a woman in a long-term sexual relationship with, and financially supported by, a man who is married to someone else," the account wrote. 

"Instead, use an alternative like companion or lover on first reference. Provide details later." 

No explanation was given for the change.
