What does impugning mean?
Impugning means formally and publicly to criticize or challenge the honesty, motives, credibility, or integrity of a person, institution, or claim. The word is especially common in legal, political, and academic contexts, where speakers may impugn a witness's testimony, an official's impartiality, or the validity of an inquiry. It is stronger and more confrontational than simply criticizing: an ordinary criticism may address quality or policy, whereas an impugnment seeks to suggest that the target is deceptive, corrupt, or unworthy of trust. Because it can seriously damage someone's reputation, impugning is generally treated as formal and sometimes deliberately careful language. The gerund form gives writers a concise way to describe such an attack: a statement may be viewed as impugning a tribunal's fairness, while an opponent may accuse it of impugning the credibility of an entire profession.

Where does impugning come from?
Impugning is the present participle of impugne, a verb borrowed from Latin impugnare, meaning “to attack” or “to challenge.” Its roots combine the Latin prefix in-, expressing opposition, with pugnare, meaning “to fight”; related roots appear in English words such as pugnacious and pugilist. The verb entered English in the early 17th century and became especially associated with attacks on character, motives, or integrity.
