pejorative
A word used as an insult or put-down.
When you call something pejorative, you're saying it's used as an insult or put-down. A pejorative word or phrase expresses disapproval, contempt, or disrespect.
Think about how differently these words feel: “old” versus “decrepit,” “unusual” versus “weird,” “confident” versus “cocky.” The second word in each pair is pejorative. It takes a neutral or even positive quality and twists it into something negative. Someone might describe a building as historic if they admire it, but call it a dump if they want to tear it down. Both describe age and wear, but “dump” is pejorative.
Words can become pejorative even if they didn't start that way. “Politician” is technically a neutral term for someone who works in government, but people often use it pejoratively to suggest someone is dishonest or manipulative. You can hear the difference in tone when someone spits out “What a politician!” versus calmly saying “She's running for city council.”
Understanding pejorative language helps you notice when someone is trying to shape your opinion through word choice rather than facts. It also reminds you to choose your own words carefully. Describing your brother's room as “messy” is honest; calling it a “pigsty” is pejorative.
