Usage
What does dishonest mean? Dishonest is the opposite of honest—it’s used to describe someone or something as intentionally deceptive or not fully truthful in some way. When dishonest is used to describe a person, it usually means they are frequently or habitually untruthful—that they tend to lie often or that they often hide or leave out part of the truth. When dishonest is used to describe a thing, it usually implies that the thing is intentionally deceptive—that it’s intended to deceive people or mislead them through lies, the omission of all or parts of the truth, or the twisting of the truth. Just as the noun form of honest is honesty, the noun form of dishonest is dishonesty. Example: The article exposes the company’s dishonest business practices and the dishonest executives who promote them.

Explanation
Someone dishonest is corrupt: a cheater, a liar, or a fraud. Dishonest folks shouldn't be trusted. If you know that being honest means to tell the truth and be straightforward, then you can probably guess that being dishonest means to tell lies and be crooked. Liars are dishonest. Criminals are dishonest. Some lawyers and politicians have a reputation for being dishonest, as do commercials that will say anything just to get you to spend your money. Besides people, certain actions are dishonest, like forging someone's signature. When you see the word dishonest, think "Untrustworthy!"
