What does cardsharp mean?
A cardsharp is a person who cheats at card games, usually relying on practiced sleight of hand — palming cards, dealing from the bottom of the deck, or marking cards — to defraud opponents rather than simply outplay them. The word combines "card" with "sharp," nineteenth-century American slang for a swindler or con artist, which also survives in phrases like "sharp practice." The term is informal and always carries a disreputable connotation: a cardsharp is a criminal of sorts, not merely a talented player. It appears frequently in writing about gambling, con fiction, and old saloon or riverboat settings. Related forms include "cardsharper" and the popular variant "card shark," though the latter is sometimes applied loosely to very skilled honest players. Knowing the word helps distinguish legitimate expertise from outright fraud at the card table.
nounA person who cheats at cards, typically by sleight of hand such as palming or manipulating cards to gain an unfair advantage.
- A person who cheats or cons others at card games, especially through sleight of hand.
"The casino security team quietly escorted the cardsharp out before he could fleece another tourist."
"Every riverboat gambler in the story seemed to be either a mark or a cardsharp."
"He learned to spot a cardsharp by watching for hands that never fully left the deck."
Regular plural; the variant "cardsharpers" takes plural "cardsharpers."
"Riverboats were notorious haunts for cardsharps preying on inexperienced passengers."
A 'sharp' was 19th-century American slang for a con artist — so calling someone a cardsharp is literally calling them a cheat with an edge.

Etymology of cardsharp
Cardsharp arose in nineteenth-century America, combining "card" (ultimately from Latin charta, via earlier European languages) with "sharp," period slang for a dishonest person or con man. The closely related form "cardsharper" appeared around the same era. The playful variant "card shark" later emerged through folk reinterpretation of "sharp," despite having nothing to do with the fish.
