What does dishonourable mean?
"Dishonourable" is a formal adjective used to describe actions, motives, or people that fall short of accepted standards of honesty, fairness, and integrity. A dishonourable act is not simply a mistake — it is one that brings shame on the person who commits it because it betrays a moral duty or exploits another's trust. The word appears most often in serious contexts: legal judgments, military proceedings, parliamentary debates, and ethical criticism of public figures. Common pairings include "dishonourable conduct," "dishonourable discharge" (a punitive form of dismissal from the armed forces), and "dishonourable intentions." Its connotations are strongly negative and carry a weight that milder terms such as "unfair" or "improper" do not; calling something dishonourable amounts to a charge against someone's character rather than their competence. In American English the word is spelled "dishonorable." For writers seeking language that conveys moral censure with gravity, few adjectives are as direct or as damning.

In military law, a 'dishonourable discharge' is the harshest punitive separation a court-martial can impose — a formal verdict that a service member's conduct was unworthy of the uniform.

Etymology of dishonourable
"Dishonourable" derives from the noun "dishonour" — formed in Middle English by prefixing "dis-" to "honour" — combined with the adjective suffix "-able." "Honour" itself entered English from Old French "honor/honour," ultimately from Latin "honor" meaning esteem, dignity, or public distinction. The word has been in use since at least the Middle English period, alongside its American spelling variant "dishonorable." Its cognates include French "déshonorable" and other Romance forms built on the same Latin root.
