A forger is someone who creates fake documents or objects that look real. They might make fake paintings, sign people's names without permission, or even create counterfeit money.
When we talk about a forger, we usually mean someone who is making something with the intention of deceiving others into thinking it's genuine. But a forger can also be a person who repairs or fixes old objects, like a metalworker who makes new parts to replace broken ones on an antique car. This meaning of forger comes from the word "forge," which means to shape metal or make something by heating and hammering. In this case, the forger is more like a skilled craftsman than a dishonest person.
A person who creates forgeries, falsifies documents with intent to defraud, e.g. to create a false will or illicit copies of currency; counterfeiter.
