means A person who deliberately deceives others, usually to take their money or property, through lies, scams, or fake schemes.

from Fraud traces back through Old French 'fraude' to Latin 'fraus,' meaning deceit, injury, or harm — a word with the sting of betrayal baked in from the start. 'Fraudster' is the modern add-on, tacking the informal, slightly contemptuous suffix '-ster' (the same one in 'trickster' and 'gangster') onto that ancient root — a 19th/20th-century coinage that made the abstract crime into a mocking label for the person who commits it.
