What Does Jack Mean?
Jack began in medieval England as a pet form of John, probably through the form Jankin, a diminutive of Jan. John comes from the Hebrew Yohanan, 'God is gracious', so Jack shares that meaning even though it has long been used as an independent name.
In English, Jack came to mean 'an ordinary fellow', which is why it appears in words such as 'jack of all trades', 'lumberjack' and 'jackpot', and why it is the hero of so many folk tales, including 'Jack and the Beanstalk' and 'Jack the Giant Killer'. The name carries a sense of cheeky resourcefulness.
Jack has been a top-25 boys' name in the US for years and is one of the most widely used boys' names in the UK. It is one syllable, hard to misspell and easy to say, and it feels as comfortable on a child as on a grandfather.
