Jack
Masculine · “God is gracious”
Jack is overwhelmingly a boys’ name — 756,943 boys against 2,734 girls since 1880. See Jack as a girl name
Jack is not short for Jacques, whatever anyone tells you. It comes from John by way of Jankin — John with a diminutive ending that English borrowed from Flemish — which wore down to Jackin and then to Jack. The evidence was set out in the nineteenth century and has held since. The name was so common afterward that it became the English word for any man at all.

The story of Jack
By the later Middle Ages John was so common in England that a name for it was needed as a common noun, and Jack became that noun: a jack is a device that does a man's lifting, a jack of all trades does any man's work, a lumberjack and a steeplejack are men defined by a job, and the jack in a deck of cards was the knave — a servant. Very few names have been that thoroughly absorbed into a language. The name itself never went away and is currently climbing again, charting in Canada, Scotland and England as well as here.
Meaning
God is gracious
The meaning belongs to John, from the Hebrew Yohanan. Jack is John plus the diminutive -kin, worn down over four centuries of use. The persistent claim that it comes from the French Jacques does not survive the medieval record, where Jankin and Jackin are both plentiful and neither is used for a Jacques.

The Kevin test
Every popular name lives one long story — a climb, a peak, a slow settling back. Jack's later chapters haven't been written yet, so we borrowed them: Kevin climbed just as high around 1963, and its whole arc is on record. Line the two peaks up, and Kevin's path sketches the road Jack is walking now.

The trade-off
- It is as short and unambiguous as a name gets, and everyone in the language knows it.
- John sits behind it as a formal option with no paperwork required.
- It has been in continuous use for seven hundred years and has never sounded dated.
- It works in every English-speaking country, and it charts in four of them at once.
- It is currently very well used and climbing, so a boy will meet others of his age.
- It doubles as a common noun and a verb in several senses, so the puns are constant and old.
- Nearly every child given this spelling is a boy; the record's girls are very few.
