Why this word
question
Impugn means to challenge the truth or validity of something, especially integrity, while question is neutral inquiry
challenge
Impugn specifically means to dispute or attack as false or questionable, while challenge is broader opposition
criticize
Impugn targets the truth or integrity of claims or character, while criticize expresses disapproval generally
Usage tip
Use when someone is casting doubt on claims, motives, or character—stronger than 'question' but less aggressive than 'attack'
