What does impeachable mean?
Impeachable means entirely free from blame, fault, or reasonable suspicion of wrongdoing. It is a formal, emphatic adjective often used to describe conduct, professional integrity, personal honour, or a public record. Saying that someone's behaviour is impeachable conveys not merely an absence of known wrongdoing but a degree of trustworthiness beyond ordinary approval. The phrase “beyond reproach” conveys a closely related idea, although “impeachable” often sounds more institutional or ceremonious. In legal and public-affairs contexts, the word can carry special force because it suggests that evidence has not merely failed to establish wrongdoing but leaves no credible basis for suspicion. It is normally used in British and American English and has a strongly positive connotation. Although relatively uncommon in everyday speech, it remains especially appropriate when describing exemplary conduct, an unblemished record, or someone who has resisted even credible allegations.

Where does impeachable come from?
The adjective was formed in English from “impeach” together with the suffix “-able.” “Impeach” came through Old French from a Latin verb meaning “to hinder or impede,” so the word's historical associations concern obstruction and prevention. That earlier sense also developed into the modern political meaning of formally accusing a public official of serious misconduct, from which the adjective came to mean “beyond blame.”
