Sense: noun/1
Crook is an informal word for someone who is dishonest, especially in a clever or underhanded way — it is broader than thief or cheat. A criminal is anyone who commits a crime, from shoplifting to murder; crook usually implies financial or trust-based dishonesty. A thief specifically takes physical property without permission. A cheat gets ahead through deception in games, exams, or business. A fraudster is more formal and uses lies — often in writing — to trick people out of money. For example, you might call a politician who accepts bribes a crook; you would call someone who steals a wallet a thief; and you would call the person who runs a fake investment scheme a fraudster.

Etymology
Crook comes from Old English crōc, meaning 'hook' or 'bend.' The word can be traced back through Proto-Germanic to an ancient root meaning 'to turn, bend.' The sense of 'a dishonest person' arose in the 1800s, based on the idea that someone who is 'crooked' in character is like something bent out of its proper straight shape.
