[ 1 syll. jac(k), ja-ck ] The baby boy name Jack is also used as a girl name, but it is much more common for boys. Its pronunciation is JHAHK †. Jack is largely used in the English and Dutch languages, and its origin is English and Hebrew. The name developed as a diminutive of the medieval name John, which had a diminutive Johnkin (Middle English) that became Jankin (Middle English) from the West Country accent. This developed into Jackin (Middle English) before being shortened to Jack.
In medieval times, the name was widely used, and it became a slang word meaning 'man'. It is well-known as the archetypal folk hero in many nursery rhymes and fairy tales such as 'Jack and the Beanstalk', 'Jack Sprat', and 'Little Jack Horner'. It has also been used to refer to real or mythical characters of otherwise unknown names, such as the 19th-century persons, the murderer Jack the Ripper and the high-jumping demon Spring Heeled Jack who became the protagonist of many Victorian penny dreadfuls and plays. The name has also been taken as an informal diminutive of James, due to its similarity in sound to Jacques, the French form of James; otherwise, the relation is not etymologically justified.
In addition, Jack is a short form of the name Jackson (English).
Jack is also a Dutch and English diminutive form of the name Jacob (Dutch, English, German, and Scandinavian).
Jack is also an English diminutive form of the name John (English and Hebrew).
