What does dishonest mean?
Dishonest is an adjective describing people who lie, cheat, or deceive, as well as the statements, actions, and practices through which such deception occurs. A dishonest witness misrepresents the facts; a dishonest business engages in fraudulent dealings. The word carries a strongly negative connotation because it attacks character rather than merely noting an error — an honest mistake is forgivable, but dishonesty implies intent. It derives from 'honest', which entered English from Old French and ultimately from the Latin 'honos' or 'honor', meaning honour or respectability; adding the negative prefix 'dis-' produced its direct opposite. In modern usage it appears frequently in legal, journalistic, and everyday contexts alike, from accusations of dishonest conduct in court to complaints about dishonest advertising. Its derived forms include the noun 'dishonesty' and the adverb 'dishonestly'.
Not honest; inclined to lie, cheat, or deceive.
"Anyone who falsifies data in a scientific paper is being fundamentally dishonest."
Often intensified with adverbs such as 'utterly', 'completely', or 'fundamentally'.
(Of conduct, statements, or practices) marked by deception or fraud.
"The company faced fines for dishonest marketing claims."
In legal contexts, 'dishonest' has a technical meaning relating to intent to deceive, central to offences such as theft and fraud.
Add just two letters to 'honest' and you get its exact opposite — 'dishonest' is one of English's most efficient reversals.

Etymology of dishonest
Dishonest was formed in English by adding the negative prefix 'dis-' to 'honest', which itself came into Middle English from Old French 'honest(e)' and ultimately from Latin 'honus' (stem 'honor-'), meaning honourable or respectable. The word has been used since late Middle English, with its sense settling on 'not honest, deceptive' by the early modern period. It shares this Latin root with words such as honor, honorary, and honest itself.

How dishonest is actually used
A strong word in both formal and informal registers: calling someone dishonest is a direct accusation of bad character, so it is often softened to phrases like 'less than honest'. Commonly applied both to people and to their actions, statements, or methods.
