'patsy' originates from American English, possibly derived from the Italian name 'Patsy,' a diminutive of 'Patrick,' used to denote a naive or gullible person.

'patsy' was popularized in the early 20th century in American slang, evolving from its use as a personal name to its current meaning.

Initially, it was a personal name, but over time it evolved into its current meaning of 'a person easily taken advantage of.'
