Where did the word "cheater" come from?
According to the Oxford English Dictionary, the first mention of the word cheater (as “cheiturs”) is from 1330. A cheater was the officer appointed to ensure that property was not left ownerless. Since lands without legal heirs reverted to the king, unprincipled men could steal from landowners, as this quote from 1656 shows: “As a Cheater may pick the purses of innocent people, by showing them something like the Kings broad seal, which was his own forgery.”
So the first time "cheater" was used meaning “someone who deceives” referred to corrupt officials who stole people’s property.
Cheaters were also those who played dice, probably because swindlers were commonly found in dice games. In an entry from 1532: “They call theyr worthy arte by a newe found name, callinge themselues Chetors.”
William Shakespeare also used the phrase “tame cheater” in 1597 to refer to decoy or fake ducks or other animals.
As early as 1607, the word “cheater” obviously meant swindler or deceiver: “Vnthrifts (Vnthrifts are the unthrifty or prodigal) cheaters and the rest of their faction..were borne downe.”
The word use continued after that time. In 1815 the word was lumped together with two others: “It is the resource of cheaters, knaves, and cozeners.” Those three words were now synonymous. Knaves were those lacking principles, cozeners were those who defrauded, and cheaters were those who, well, cheated.
