Meaning and origin of Jax
Jax is an American (modern coinage) and English name that is usually said to mean “short for Jackson, son of Jack”.
Jax is a modern American name that began as a short form of Jackson, meaning "son of Jack," and can also shorten Jaxon or Jaxton. Jack itself developed in medieval England as a pet form of John, which goes back to the Hebrew for "God is gracious." Jax has become a standalone name in recent years, popular with parents who want something short, punchy and distinctive. The X ending gives it a contemporary edge, and it is often seen as a tough, energetic choice. Jax is easy to spell once learned, and it pairs well with longer, traditional middle names.
