Etymology
Origin of impugn
1325–75; Middle English impugnen < Middle French impugner < Latin impugnāre to attack, equivalent to im- im- 1 + pugnāre to fight, derivative of pugnus fist; see pugnacious
Explanation
To impugn means to call into question or attack as wrong. If your usually grumpy brother is suddenly nice and sweet, you'll impugn his motives if you're smart — he probably just wants something from you. The root of impugn is the Latin pugnare which means "to fight," so when you impugn, you are fighting or attacking, but by saying that something is false or wrong. If a candidate has a record that cannot be impugned, his or her opponent might go for a character attack. If you take pride in your work, you will be especially insulted if someone impugns your professionalism or integrity.
