'cheat' originates from Old French, specifically the word 'escheat', where 'es-' meant 'out' and 'cheat' meant 'to fall'.

'escheat' transformed into the Middle English word 'cheten', and eventually became the modern English word 'cheat'.

Initially, it meant 'to fall or happen by chance', but over time it evolved into its current meaning of 'deceiving or tricking someone'.
